A teen is under arrest morning after a midnight, masked robbery attempt at a Lower Sackville pizza joint.

RCMP report a man, wearing a mask, entered the Primo Pizza restaurant on Cobequid road around 11:24 p.m. Wednesday.

He unsuccessfully attempted to rob staff and sprayed a mace-like substance in the restaurant before leaving and running away on foot.

Police searched the Caudle Park and Glendale Avenue area, with a K-9 unit, for about two-and-a-half hours before arresting an 18-year-old man on Chandler Drive.
