Police say a suspect wanted in connection with two robberies in Lawrence County has been taken into custody. The Shenango Township Police Department says 46-year-old John Graham Jr. was arrested overnight after the Shenango China Federal Credit Union in New Castle and the Last Minit Mart in Shenango Township were held up on Wednesday. According to New Castle Police, the Shenango China Federal Credit Union in the Town Mall was robbed just after 3 p.m. Wednesday. The suspect was believed to be driving a white cargo van with ladder racks.  Then, later last night, Shenango Township Police say the Last Mini Mart on New Butler Road was held up. Police say the suspect was armed with a knife and left in what appeared to be the same white cargo van as the New Castle robbery. Shenango Township Police say Graham is charged with robbery, theft by unlawful taking, receiving stolen property, terroristic threats, reckless endangerment and simple assault.
