New Delhi, Sep 7 (IANS): Three minor boys have been arrested for the murder of a 19 year old man identified as Mandeep, in Shahdara's Vivek Vihar area, the police said on Saturday.

The accused minors allegedly stabbed Mandeep to death over personal enmity.

According to the police, the deceased used to work as an air conditioner repair mechanic.

A senior police official said Mandeep went out of his house on Monday for some work and did not come back. Subsequently, his family on Tuesday reported the matter to the police and a missing complaint was lodged.

Another boy told the police that Mandeep had beaten him some time back and he wanted to take revenge and for that they called Mandeep on Monday and then killed him, police said adding that further investigation is underway.
