Lehigh County's district attorney said Thursday he's closed his investigation of a prison inmate's death, and he said no charges will be filed.

Alphie Herrera died in February following a struggle with prison officials inside the Lehigh County Prison in Allentown.

Herrara suffered an apparent seizure while being physically restrained, the coroner said.

District Attorney Jim Martin said corrections officers and medical staff did what they had to do to control Herrera after he suffered the seizure and became combative.
