A man on the run from Welsh police has used Facebook to taunt police officers trying to track him down.

Logan Rhys James, of Caerphilly, South Wales, was in prison for a street knife attack but was released early.

Gwent Police, who are hunting him because he breached the terms of his release, issued the 19-year-old's mugshot on Facebook as officers tried to track him down.

But a comment appeared, apparently sent from James' profile, which said: "Haha catch me if you can wont (sic) see me slipping."

Officers said they remain confident of catching the teenager, who is known to have contacts in Caerphilly and Barry.

A spokesman said: "Logan received an eight-month sentence for affray after being convicted on 31 July 2014.

"Due to the fact that Logan, who was released on licence, breached his licence conditions he has been recalled to prison."
