Two thieves are on the run after being identified as the duo who robbed the same Florida baby store 13 times.

John Grassano and Sean Loychick allegedly stole as many as 50 breast pumps and multiple baby monitors from Babies "R" Us.

"They would bring bags in with them in their clothing and they would conceal the items in the shopping bags," said police spokeswoman Shannon Cake. "Then one or the other would just walk out with the bags."

The pair were arrested for shoplifting and released last month. While in custody, Grassano told police that he was selling the merchandise on eBay for between $149 and $379, making the scam worth a total of $15,000.

Authorities also suspect that they may be responsible for other baby store thefts in the South Florida area.
