A 12-YEAR-OLD boy was at Tiong Bahru Park with two of his friends when a group of six teens confronted him on Wednesday afternoon.

The gang accused the boys of having assaulted one of their member's younger brothers.

The teens, aged 12 to 20, asked the boy and his friends to surrender their belongings, which included $30 in cash and a $500 mobile phone.

The teens then punched one of the boys in the eye and slapped another in the back before fleeing.
