Charleston police on Tuesday arrested a woman accused of using a wheelchair to steal more than $800 worth of merchandise from a West Ashley Kohl's store.

Mary Sue Tolliver, 31, of Heatley Street in North Charleston, is charged with armed robbery in connection with the incident. She was being held Wednesday at the Cannon Detention Center.

Tolliver was one of two people who robbed the 2245 Ashley Crossing Drive store around 2 p.m. Tuesday, according to an incident report.

Surveillance video showed a woman pushing a man through the store in a wheelchair. The woman stuffed a pair of sandals and a bra into her purse, police said. Other items made their way under a white sheet that the man had draped on the seat of the wheelchair, according to the report.

An employee chased after the man and woman as they exited the store, police said. The pair ran toward a maroon-colored car that was waiting in the parking lot, but police said that vehicle took off upon seeing that they were being followed.

According to the report, the man then yelled that he had a gun and would shoot the employee. The employee ducked behind a car for cover, before pursuing the man and woman once again, police said.

The woman fell to the ground as the employee caught up to her, the report said. The man then threw all of the merchandise, 18 items worth $812, to the ground and ran toward Magwood Avenue, police said.

The woman, who police later identified as Tolliver, was taken into custody and transported to the county jail. Authorities are still searching for the second suspect, Charleston police spokesman Charles Francis said.
