The deaths of four people in Barnsley which are possibly due to heroin are not believed to be linked to two drug-related deaths in West Yorkshire, according to police.

Four people were found dead at separate addresses in Barnsley on Good Friday, though South Yorkshire Police now believe one of those deaths was linked to a pre-existing medical condition.

Reports of two more people becoming "gravely ill" after taking suspected illegal substances were also received by South Yorkshire Police on Monday but both survived, the force has revealed.

Ch Supt Rob Odell, from South Yorkshire Police, says: "I appreciate that these are concerning events and I’d urge anyone with concerns about this matter to either contact police or, if you have taken a substance and feel unwell, to seek medical support and advice immediately."

We now have more details on the large blaze at a former golf course near York this morning.

About 20 firefighters were called to an outbuilding at the site of Allerthorpe Park Golf Club, near Pocklington, at about 08:00.

The fire affected an area about 5m by 20m, and thick black smoke was pictured drifting over Melbourne Road and nearby land.

The building at the centre of the blaze contained agricultural machinery and lawn mowers, according to Humberside Fire and Rescue Service.

It's not thought anyone was injured in the blaze and firefighters are currently damping down at the scene.

In the last half-hour, two former party leaders with South Yorkshire constituencies have announced their intention to run again in the general election.

Nick Clegg says he will defend his Sheffield Hallam seat for the Liberal Democrats.

Mr Clegg says he has a "huge loyalty and attachment" to his constituency.

He says the Prime Minister's decision to seek a snap election on 8 June is "opportunist, in order to secure a landslide and impose a hard Brexit":

Meanwhile, Ed Miliband is to stand again for Labour in Doncaster North.

Mr Miliband stood down as leader of the Labour party after being defeated at the last general election in 2015.

One lucky swimming fan got a surprise at Ponds Forge in Sheffield yesterday.

It came after Olympic champion Adam Peaty secured a place at swimming's World Championships, posting a qualifying time for the 100m breaststroke as he took the British title.

Afterwards he gave his medal away to young fan Harry Brancham, a keen club breaststroke swimmer himself with clubs in Retford and Bassetlaw.

Peaty says he wants to help inspire future generations:

It's 84 not out for one of South Yorkshire's most famous sons today as Dickie Bird celebrates his birthday.

The former cricket umpire may be easy to recognise these days (it helps if you've got your own statue in the middle of Barnsley), but how about as a young lad? 

The Barnsley Archives have unearthed this gem of the boy Bird. Happy Birthday Dickie!:

Svitlana Krasnoselska, 40, who's also known as Lana and is originally from Ukraine, was last seen in Micklefield at about 05:00 on Monday 3 April. Since then, nothing's been heard from her.

Yesterday, police issued CCTV images of her at work in Leeds on 17 March in a bid to jog someone's memory.

Now officers says it's thought she may have some contacts in York and they're keen to hear from anyone there who may have seen her.

Det Insp James Entwistle says: "We remain very concerned for her welfare and urgently need to find out where she is."

Sixth form and college students in Sheffield could lose their free bus passes if the city council gives the go-ahead to planned changes to travel schemes later today.

The move would also see families asked to contribute more than £500 per child for students with special educational needs.   

Sheffield City Council is one of only a small number of authorities which still offers free school or college transport for young people.

The authority says families who qualify will be able to apply for a bursary to cover the extra cost.

But families of students who currently get free special educational needs transport will be asked to pay £540 per year to cover the cost. 

It currently costs about £300,000 to help provide the service, the council says.

A reward of £4,000 has been offered to anyone who can help police find out more about the death of a rare red kite in North Yorkshire.

Police say the bird of prey was found near Greenhow, in Nidderdale, on Saturday 11 March and an examination revealed its carcass contained what's believed to be lead shot.

Three rewards worth a total of £4,000 have been offered for information leading to the arrest and charge of anyone involved in the killing.

The money's been put together by local residents, businesses and organisations such as the RSPB and Crimestoppers.

It's taken many years to reintroduce red kites to the UK after their near-extinction. They have special legal protection under the Wildlife and Countryside Act.  

Anyone with information is asked to contact North Yorkshire Police.

It looks like this bobby in Harrogate has been giving a lot of thought to symbolic barriers this morning:

Dilapidated former mill buildings in Leeds could be brought back to life under plans to regenerate the city centre's riverside area.

The proposals for Hunslet are part of a masterplan to transform the South Bank area of Leeds.

They include bringing the Hunslet and Victoria Flax Mills (pictured) back into use, and building a new bridge across the River Aire. 

In 2015, the Victorian Society cited the city's Hunslet Mill and Victoria Works as one of the top 10 most endangered Victorian and Edwardian buildings in England and Wales.  

Plans to build a new secondary school on a former landfill site in Sheffield have been approved.

The £25m secondary school and sixth form (artist's impression above) on Carter Knowle Road will create 180 school places by September 2018, according to Sheffield City Council.

Campaigners against the proposed Bannerdale school say the fact the land was previously used for landfill (pictured below) creates an "unnecessary risk of potentially explosive and flammable toxic gases".

A public meeting in March, which was attended by just over 100 people, also raised concerns about the loss of green space, with the proposed school site taking up a large chunk of land which is currently available for public use.

Organisers have confirmed that uncertainty around the hall's restoration project, which is yet to properly begin, has played a part in their decision to move the competition elsewhere for good.

Scientists are warning an asteroid thought to be the size of a famous Yorkshire landmark is due to pass the Earth later today.

The last time an asteroid this size came as close to our home planet was back in 2004. 

Stay calm though, there's no need to panic: it's passing us at five times the distance of the moon.

Mike Shaw, an astronomer from Bootham School in York, has tried to give us a little context, by comparing the asteroid's size to a very well-known place in Scarborough:

Starting fine but chilly, with some hazy sunny spells possible. 

Cloud amounts gradually increasing from the west, perhaps delivering a few spots of rain on hills later.  

Tonight, it'll be fairly cloudy with perhaps the odd spot of rain over hills. Some clearer spells are likely by dawn.

Senior councillors are being asked to approve a multi-million pound deal to revamp Headingley stadium in Leeds.

If the scheme's approved, visitors will bring in more than £7.5m to the city by 2020, according to Leeds City Council officials.

The deal's been brokered by the council and involves a private investor putting up £35m.

Yorkshire County Cricket Club had warned that without the redevelopment, it would lose the chance to host international matches.
