New Delhi, Aug 24 (IANS): A 17-year-old boy was stabbed to death here by his four friends over a trivial issue, police said Saturday.

Ravi, who was reported missing, was Friday found murdered near a mall in Mayur Vihar in east Delhi, police said.

According to a police officer, Ravi was missing from his house after he went out to meet his friends Thursday.

When Ravi's parents approached police the next day with a complaint that their son was missing, the investigators showed them a body which they had recovered. Ravi's family identified the body, police said.

Ravi was Thursday called by friends for consuming liquor but an argument broke out between them over a trivial issue and he was stabbed to death with a broken bottle of beer, police said.

The victim's friends disfigured his face with a heavy stone so that the body could not be identified, police official said.

"We nabbed all the four accused, who live in the same area, Friday night," said a police officer.
