Three sisters are accused of stealing more than $1,600 worth of baby formula from a Walmart store on Valentine's Day and police allege they attempted to take more of the product from other locations.

Durham Regional Police say the alleged incidents began at a Walmart on Baldwin Street South in Whitby, where two women tried to leave the store without paying for more than $1,200 worth of baby formula on Saturday. An alarm went off and they fled to a car, which was being driven by a third woman. The formula was left behind, police say.

Soon after that incident, police say the same three suspects went to a Walmart on Laval Drive in Oshawa. It is alleged they were "captured on store surveillance" stealing baby formula that was worth more than $1,600.

Police say the same suspects were then spotted at a different Walmart in Oshawa, on Harmony Road North. Store security called police, but the women left the store and they also left behind a cart with baby formula in it. They were arrested in their vehicle.

Police say the accused are 19, 25 and 26 years of age, respectively.

A 19-year-old Toronto woman faces two counts of theft under $5,000 and two counts of possession of stolen property under $5,000.

A 25-year-old Brampton woman faces one count of theft under $5,000, two counts of possession of stolen property under $5,000 and a count of failing to comply with a probation order.

A 26-year-old Ajax woman faces two counts of theft under $5,000 and two counts of possession of stolen property under $5,000.

None of the charges have been proven in court.
