A man has been sentenced to two years in prison after admitting to smashing a pint glass into his victim's face in a London pub, The Sun reports. Police treated the incident as a homophobic attack.

Disturbing CCTV footage shows Anjungi Lam, 35, attacking his unnamed victim, 23, at the Kentish Drovers pub.

The attack occurred March 5 after the victim arrived holding hands with his 20-year-old boyfriend.

Lam ran toward the victim and smashed a pint glass against the right side of his face, cutting his nose, lip, and neck. The victim's tooth was chipped and his cornea was also injured. Flying pieces of glass also hit the victim's boyfriend in the eye.

Lam, who fled the scene, was arrested May 19 and subsequently charged. He had worked for the pub for three months before being fired for lateness.

“This was an entirely unprovoked incident," says investigating officer PC Lance Sharrock. "Lam did not know the victim or his partner, they had not spoken nor had any disagreement to provoke such a violent attack."

“The victims felt Lam must have been motivated by homophobia as they entered the pub holding hands and we began a hate crime investigation," Sharrock continues. “Lam was quickly identified and I am pleased at his sentence which shows that incidents of this nature will not be tolerated.”

Lam's charges include actual bodily harm, assault by beating, and having an offensive weapon. He was jailed for an additional year for unrelated offenses.
