"If what Victoria's Secret is saying proves to be true, this is a pretty significant arrest," said Trooper Jonathan Sunderlin, community services officer in Media.

More than a week ago, state police began looking for a gray Dodge Magnum with Rhode Island plates after employees reported a theft from the Victoria's Secret at the Granite Run Mall.

So, on Sunday afternoon, when employees reported another theft, troopers were able to quickly spot the vehicle leaving the mall and arrest the three men inside, Sunderlin said.

Police searched the car and found the bras, as well as fake receipts, cut-up security tags, money, and gift cards, he said.

One man, Paul Mathurin, 23, was from Brooklyn, but the addresses of the others, Yvon Duvergil, 22, and Andre Samuel, 25, were uncertain because they had provided false names and birthdates, Sunderlin said.

Some marijuana was also found in Duvergil's possession, he said.

A fourth person, Danielle Vann, 23, of Philadelphia, was arrested inside the mall while carrying Victoria's Secret bags, merchandise and receipts, Sunderlin said.

All four were arraigned Monday on theft, conspiracy and other charges, and sent to Delaware County Prison.

They may have been behind a string of theft and fraudulent transactions that have ripped off Victoria's Secret stores for an estimated $600,000 to $1 million, an official with the company's loss-prevention unit told state police.

News reports over the last two years tell of Victoria's Secret thefts from Connecticut to North Carolina to Ohio - as well as a $10,000 panty heist last month in Washington state.

On Valentine's Day, about 250 pairs of women's undergarments, including $1,875 worth of thongs and briefs, were stolen from a Pottstown Victoria's Secret.

The crimes included not just theft but also sophisticated attempts to return stolen merchandise for cash or gift cards, using fake receipts, Sunderlin said.

Limited Brands, the parent company of Victoria's Secret, declined to comment about the Granite Run Mall case or others.

"To protect our associates, customers and assets, Limited Brands has and will continue to work aggressively with law enforcement authorities to address acts of theft committed in our stores. For obvious security reasons, we cannot discuss the specific measures we are taking," said spokeswoman Jennifer Ortiz Brown.
