Armed police sealed off London Central Mosque, in Regent's Park, as part of the search.

The Metropolitan Police has dismissed suggestions from Ukip leader Gerard Batten that water cannon could be deployed at protests to "provoke Brexiteers".

The force, which does not own any of the machines, said reports it could use them at Brexit rallies were "baseless and false".

Mr Batten is due to speak at a rally alongside ex-English Defence League chief Tommy Robinson against "Theresa May and her traitorous Tories" on Whitehall this afternoon.

Westminster is expected to see mass protests and counter-protests on the day the UK was scheduled to leave the EU.

Road closures may be enforced around the area, Transport for London warned.

Westminster Council said it is aware of up to 13 separate scheduled protests and the Metropolitan Police said "appropriate policing plans are in place".

Mr Batten, Mr Robinson and "other prominent Brexiteers" are due to speak on stage at a rally on Whitehall at about 16:30.

Mr Batten had tweeted: "There are reports that water cannon may be deployed tomorrow in London, and that some of the police may try to aggregate and provoke Brexiteers.

"There is always the danger of provocateurs planted to cause trouble. I hope it is not true but I call on everyone present to be peaceful."

The Tottenham striker, a New England Patriots fan, watched them win a sixth Super Bowl in Atlanta in February.

Extra officers have been drafted in to help deal with "numerous" planned protests around Westminster later today.

The Met says it has "appropriate policing plans" in place and will be ready to react to "any incidents" or spontaneous demonstrations.

A spokesman said: "We will always provide a proportionate policing plan to balance the right to peaceful protest, while ensuring that disruption to communities is kept to a minimum.

"To date, protests have been largely peaceful and we have no intelligence at this time to suggest that will change."

The detective who led the inquiry into Jill Dando's murder has told the BBC her case will never be solved.

Hamish Campbell told a documentary to mark 20 years since the newsreader's shooting: "Do I think somebody will come back to court? Probably not, no."

His team arrested Barry George in 2000, one year after Dando, 37, was killed on her doorstep in Fulham, west London.

Mr George was convicted of murder and spent eight years in jail, before being acquitted at a retrial and released.

Barbecues are to be banned at the London Fields in Hackney due to the "high volumes of rubbish" left in the area, according to Hackney Council.

The authority estimates that it costs up to £200,000 to manage the park during the summer months.

Hackney Council says increased popularity of London Fields has led to scorched grass, littering and high volumes of rubbish, illegal trading, aggression and intimidation towards staff, and people urinating in public.

Cllr Feryal Demirci said: "Suspending the use of barbecues in London Fields isn’t a decision we take lightly, as we know it’s one of the many reasons people visit the park during the summer.

"However, our monitoring shows that barbecues in the volumes we see in London Fields could potentially be causing harmful levels of particulate matter pollution and are also contributing to unsustainable management issues in the park.

"We’ll monitor air quality and other issues at London Fields this year and review the decision in late 2019."
