Levi Davis, a former Bath player, was seen leaving a pub in the city on 29 October.

The 25-year-old - who was once a contestant on Celebrity X Factor - has not been seen since and last month fears were raised that he may have drowned.

His family said that an investigation by police had suggested that his phone had last been detected at the far end of Barcelona's commercial port.

Catalonia's police force, Mossos, released footage on Thursday showing officers in a boat searching the area.

The force said it was part of an investigation into the disappearance of a man on 29 October - though they did not name Mr Davis.

In a statement, the force said: "We continue to investigate the disappearance of a man in Barcelona on 29 October.

"We [have] activated the Maritime Police and the Aquatic Unit to search the port of Barcelona and the Llobregat Delta.

"The case remains open."

It comes after family members shared details of the investigation, including reports that cruise ship staff had tried to save a man in the water on the night Mr Davis went missing.

In a statement, they said: "Four staff confirmed seeing a man in the water with specific details including him asking for help in English and the colour of his clothing.

"A life jacket was thrown from the ship and emergency sea and air rescue services searched the area but they were unable to find him."

In February it was reported that Spanish police felt the case had "disturbing" issues with "no logical explanation" for his disappearance.

Mr Davis, a former Bath player, appeared on Celebrity X Factor in 2019 - forming a singing group with fellow rugby stars.

He was also on E4's Celebs Go Dating a year later.

Mr Davis had signed a record deal and had gone to stay with his friend Richard Squire in Ibiza to work on some songs.

While he said he would contact Mr Squire when he arrived in Barcelona, he never did.

Mr Davis was wearing a white T-shirt, black jeans and white trainers and carrying a small black backpack at the time of his disappearance.

His passport was found by Spanish police a few weeks later.

A private investigator has been helping the family - and a £10,000 reward was offered for information leading to his discovery.
