A woman was robbed at gun point Monday in the 400 block of Cairnsmore Street.
The woman was walking alone around quarter to 6 Monday evening when she was approached by a lone man with, what appeared to be a handgun.
He made off with her purse and fled.
The victim went to a nearby home, called 9-1-1 and police dispatched patrols to the area right away.
Police say, due to the seriousness of the offence, a lot of resources were assigned to the investigation and after a short, but intense investigation, a suspect was identified.

A 17 year old teenager was arrested without incident the next day.

The firearm turned out to be a replica BB Gun.
