The Gazette made an appeal in February after Borex Tatsa, 18, went missing from his home in Hackney on Saturday February 7.

But sadly his body was discovered three weeks later on Saturday February 28 in the River Thames close to Rotherhithe.

His death is being treated as unexplained and detectives have now released CCTV images of the last moments he was seen alive in a bid to hear from anyone who may have seen him before his death.

Borex was last captured on CCTV on the 149 night bus and then in Southwark at 1.20am on Sunday, 8 February.

His rucksack was found nearby, on the same day, in a bin outside The Old Thameside Inn.

His mother said: “Borex was a much loved member of our family.

“He was a quiet person with a lovely smile. If anyone knows anything at all about what happened to him please come forward and tell the police as we are desperate to know what happened to him.”

Det Insp Ian Fleming, from Hackney’s public protection unit, added: “The circumstances surrounding the discovery of Borex’s body in The River Thames remain unexplained at this stage, with all options remaining open.

“I would like to appeal to any witnesses or any person who has information in relation to this incident, to come forward and speak to a member of the investigation team.”

Anyone with information is asked to contact the investigation team at Hackney CID on 020 7275 3404 or Crimestoppers anonymously on 0800-555-111.
