Police were called to the St Clair Street Shoppers around 5:30 yesterday afternoon when a 37-year-old man allegedly tried to steal a dash cam and back massager.
He was arrested and charged with theft and possession of stolen property.
A few hours later, officers were back making another arrest when a 31-year-old woman tried to get away with a tablet and audio system hidden in her bag.
As it turns out, police say the suspect in that case was also wanted on an outstanding warrant in Sarnia.
She was held in custody until Sarnia officers could arrive.
