Police say the suspects drove through Goldfinch Park in a car, hurling insults at the seniors and ordering them to leave or they'd be killed. The seniors told police one of the suspects used a megaphone to yell at them.
"They were using Mom and Dad's car to harass other people's grandparents," said Abbotsford Police Cst. Ian MacDonald.
On July 18, police stopped a car with four occupants near the park. One of the passengers appeared to be raising a megaphone to his mouth.
Amarprit Singh Dhaliwal, 19, Gobind Denzil Pangli, 19 and Suraj Narang, 18, are charged with uttering threats and causing a disturbance. A 17-year-old has also been charged but can't be named.
