Two teens, one from Stoughton, and the other from Easton, were arrested by Easton Police Monday after allegedly robbing and assaulting another teen.

Michael Bunce-Grenon, 19, of Dennison Court in Stoughton was charged with assault and battery with a dangerous weapon and robbery. A 15-year-old Easton juvenile was arrested on the same charges.

Police Chief Allen Krajcik said the incident occurred March 4 at approximately 4 p.m. near Frothingham Park in Easton.

"Easton Police Officer Beverley McRoberts was on patrol when she was flagged down by a 15-year-old male who stated he had just been beaten and robbed at Frothingham Park in North Easton," Krajcik said.  "He stated that he was with a group of males at the park when he was attacked by several of them.  Money was taken and one of the suspects pulled a knife on the victim. The victim was kicked and punched by several of the males."

Bunce-Grenon was held on $5,000 cash bail and was transported to the Bristol County Jail on Ash Street in New Bedford. 

Krajcik said more arrests are likely.

He said the victim received minor injuries but refused medical treatment.
