A 16-year-old boy was struck over the head with a baton during a daytime street assault in North Delta on Tuesday. Four teenage boys were subsequently arrested.

Const. Ciaran Feenan, of the Delta Police, said a North Delta resident called police about a fight out in front of her home, in the 11200-block of 82A Avenue.

She told police a person was being hit with what appeared to be a baton. The victim sustained cuts to his head that weren't considered to be life-threatening.

When police arrived at the scene they found four boys trying to hide and one of them had a baton. Feenan said the four were taken to police headquarters. Two were released on a promise to appear in court and two were released pending further investigation, Feenan said.
