Boxing star Anthony Joshua warned a group of students to “watch your mouth” after they taunted him from an upstairs window.

The former WBO and IBF title holder, who grew up on the Meriden estate, was filmed in a Loughborough University student flat telling the youngsters he’d start “cracking jaws”.

The Sun newspaper reported that Joshua, who trains at the university, had been heckled about avoiding a fight with Tyson Fury as he walked past the building.

A source told the paper that “lots of profanity and abusive language” was hurled at Joshua from an upstairs window.

The boxer then pressed the halls' external buzzer and was allowed in, where he confronted the group.

In the video, he is heard saying: “Remember you’re running your mouth because when I start cracking your glass jaws, none of you will like it.

“When your jaws start breaking and people start chasing you outta this uni, none of you will like it.

“Watch your mouths, because you don’t know who you’re talking to sometimes.”
