Hamilton police say they're investigating another mugging in Ancaster and whether it is possibly linked to a birthday basketball game that was interrupted by assault and robbery over the weekend.

The incident happened last Thursday around 4 p.m., a couple of days before the basketball game mugging. In this incident, a 14-year-old boy was sitting in a field south of Golf Links Road, near Joshua Avenue in Ancaster when two older teen boys came up to him on foot, police said.

They asked if they could buy drugs, and then demanded the 14-year-old turn over his smart phone and BMX-style bike. They got away with the phone and headed east toward restaurants and businesses. The 14-year-old wasn't injured.

The 14-year-old told police he observed something in one of the boys' waistband, which he thought could be the handle of a handgun or a pellet gun.

Both suspects are described as black and around 17 years old, police said.

In the basketball incident, a group of 10 youths playing at the nearby Meadowlands Park, were mugged by three older teens who came up on bikes and demanded the boys turn over smart phones. One fought back and was assaulted, Hamilton police said.

"It is not known if these incidents are linked but given the proximity and time of the offence, police are considering the possibility that [the] same suspects (were) involved," said Hamilton police Const. Stephen Welton.

Police ask anyone with information to call police or Crime Stoppers.
