Authorities arrested a College Park man after an explosive device was neutralized in the city Friday morning, the second time a bomb was found in the city this week.

John Frank Jenkins, 28, of the 9000 block of Rhode Island Avenue, was arrested and charged with two counts of manufacturing or possession of an explosive device after police discovered a hazardous device in a van parked on the 5000 block of Edgewood Road, about a mile north of the University of Maryland, at 4 a.m.

The Prince George's County Fire and EMS Department's bomb squad disabled the device, and nearby residences were checked for any other explosives, but none were found, authorities said.

Friday morning's incident followed an ongoing investigation of a pipe bomb at a home on the 8800 block of 48th Avenue on Tuesday. Authorities described the device as a small pipe bomb that exploded on a front porch, causing minor damage. Spokesman Mark Brady said the two incidents are believed to be linked.

Police arrested Jenkins and executed a search warrant at his College Park home later Friday morning. A female resident of the home was also arrested on an unrelated open warrant, according to Brady.
