Police are investigating whether the armed robbery of a Brinks truck on Tuesday outside a Philadelphia-area store is related to four other attacks on armored vehicles in and around the city this summer.

Armed thieves are accused of stealing an estimated $700,000 from a Brinks driver, less than two months after $2 million was stolen from another armored vehicle.
