A second man has now been charged, in connection with alleged armed robbery incidents in Petrolia and Sarnia this month.
OPP recently arrested a 40 year-old Sarnia man in Lambton County, on two counts of robbery with a weapon.
A 46 year-old Sarnia man was earlier charged with two counts each of robbery with a weapon, using a disguise with intent to commit an indictable offence and possession of a weapon for a dangerous purpose.
OPP say a convenience store on Petrolia Line was robbed on May 14th, and Sarnia Police say a Wellington Street convenience store in the city was targeted on the 16th.
They say witnesses in both investigations identified the accused.
