Tracey Hanson's son was fatally stabbed at a London bar in October 2015.

21-year-old Josh was with his girlfriend when he was attacked and three months on, no one has been charged.

Tracey says she struggles each morning to come to terms with what happened to her son.

"Every single thing I do, I think of Josh...Sometimes I can't even look at the photos because it just hurts so much", she says.

An appeal for information appeared on the BBC's Crimewatch programme in November with police requesting information from the public on the attack.

Anyone with information can call Crimestoppers anonymously on 0800 555 111 or via crimestoppers-uk.org.
