A VIOLENT lag recorded a song in his prison cell mocking his victim.
Darren Curwen, 29, used a banned mobile for the YouTube video, since seen nearly 2,000 times.
Smirking songbird Darren Curwen, 29, strummed on his guitar after penning the lyrics to ‘Plastic Plates’.
The amateur boxer sings: “When I first came to jail I was looking pale, because the f***ing judge he wouldn’t give me bail.
“What’s a guy like me doing in this place, on a section 18 GBH, I didn’t use a weapon and I didn’t use a knife, I just beat the poor f***er to an inch of their life.”
The amateur boxer got five years for GBH in 2018.
Curwen had also hurled a TV, table and model Dalek at ex-work pal Michael McLaughlin.
Curwen accused him of grassing over an assault.
The clip was filmed at Category C Wealstun in Thorp Arch, West Yorks.
Curwen, of Workington, Cumbria, posted: “Hope you enjoy it as much as I enjoy playing it.”
The Ministry of Justice has been asked to comment.
