Bristol family appeals for leads on missing Jack O'Sullivan

Jack O'Sullivan was last seen on CCTV in the Cumberland Basin area of Bristol

The parents of a missing 22-year-old man who failed to return home after a house party 10 days ago have appealed for information.

Jack O'Sullivan was last seen walking near Bristol's city centre, along Brunel Lock Road, at 03:15 GMT on Saturday 2 March.

He had attended a birthday party in Hotwells.

His mum Catherine O'Sullivan said: "We just need to know where he's gone, for our sanity."

"We've been able to ascertain his movements of leaving the party at around 02:53, seeing him attempt to stop taxis and Ubers, and trying to get a lift on two occasions," she said.

Police believe Mr O'Sullivan may have captured on CCTV at about 05:40 GMT (indicated by the red arrow)

Mrs O'Sullivan said she had waited up for her son but fell asleep after receiving a text from him at 01:52, assuring her he would find an Uber home.

At 03:24, Mr O'Sullivan had attempted to make a call to a friend who was still at the party.

When the friend called back 10 minutes later, Mr O'Sullivan answered but only managed to say "hello" before the line went dead, Avon and Somerset Police said.

However, his phone remained active on the Find My Friends app up until 06:44.

"To go off camera and vanish is one thing, but the phone for us, as awful as this terrible situation is, is the big unanswered question," Mrs O'Sullivan said.

Police have released a CCTV image showing another possible sighting of Mr O'Sullivan, spotted near Hotwell Road at about 05:40.

Mr O'Sullivan's parents Alan and Catherine O'Sullivan urged anyone with information to come forward

On Friday 8 March, police divers were seen searching the River Avon, but it has not been confirmed whether it was linked to the missing 22-year-old.

"If there's anybody out there, with even the smallest piece of information that might jog somebody's memory," Mrs O'Sullivan continued.

"Did I notice something on the floor? Have I seen a phone dropped and smashed? Or if somebody picked up a phone but they don't want to come forward, because they think it would be incriminating.

"We just want to know why that phone was still active, because it doesn't fit with anything else that we have to go by."

Avon and Somerset Police has appealed for anyone who may have been driving in the Cumberland Basin area, or who may have dashcam footage, to come forward.

Mr O'Sullivan is described as white, about 5ft 10ins (178cm) tall, of slim build and with short, brown hair.

He was last seen wearing a quilted green/brown Barbour jacket over a beige woollen jumper, navy chinos and brown leather trainers with white soles.
