In December, the District Attorney's Office cleared police of any wrongdoing, with District Attorney David Heckler saying that the Taser was used to prevent Joey Williams from running onto nearby Route 13. The injuries likely occurred when Williams fell onto his face during the incident, Heckler added.
The FBI does not comment on the status of investigations, spokeswoman Carrie Adamowski said Friday. But a statement on the Tullytown Police Department's Facebook page, signed by Chief Daniel Doyle and posted Thursday, said the agency had closed its review and cleared the department.
A message left for Williams' Center City attorney was not immediately returned. The family had previously said it was considering a civil suit against the police.
Williams agreed with authorities to enter a diversion program that will wipe the shoplifting charges from his record if he stays out of trouble.
Williams' mother, Marissa Sargeant, was arrested last month for shoplifting at the same Walmart where her son was subjected to the Taser. Court records say she is still in Bucks County Prison, with a formal arraignment scheduled for later this month.
