DETROIT, Mich.- The hunt continues for two men linked to cross-state jewelry store heists.
The FBI is releasing new surveillance pictures after Medawar Jewelers and Tapper's Fine Jewelry were robbed back in April.
“These are dangerous individuals,” David Porter of the FBI said.
David Briley, Shaheed Calhoun, Orlando Johnson and Nathaniel Pembrook are the men police believe are behind the Rolex targeting crime spree. They’ve been arrested and were federally charged in Detroit.
“We believe ultimately that 6 men were responsible for these robberies,” Porter said. “So far all of those men have been arrested and are currently in custody, all four of those men are from the Philadelphia area.”
The FBI believes the two suspects still wanted are from the Philadelphia area as well. They're now offering a $10,000 reward for information that leads to an arrest.
“We believe these men are connected to each other so seeing all five photos together may jog someone’s memory about their association with one another,” he said.
Pembrook is believed to be the man who pointed a gun at the employees in Medawar Jewelers; it’s believed he was shot in the store, and DNA results led investigators to him.
The FBI has yet to identify which role each of the two fugitives played in the crime spree, only saying the two suspects are still at large and are considered armed and dangerous.
“These are brazen acts and it's important to know that law enforcement is still very diligently working this case and we're not going anywhere, we're going to keep at it,” Porter said.
