Lebanon ? Investigators are looking into whether a car bomb that killed one of Lebanon’s top terrorism investigators was part of a string of attacks that have targeted leading anti-Syrian politicians, a security official said Saturday.

Police collected fingerprints and bits of shrapnel in search of clues at the site of the Friday bombing that killed Capt. Wissam Eid. Among other things, they hoped to learn who owned the car.

“Security and judicial police investigators are probing a possible link between Capt. Eid’s killing and a series of assassinations that have rocked Lebanon in the last three years,” the official told The Associated Press. He spoke on condition of anonymity in line with government regulations.

Eid was one of the country’s top terrorism investigators who was probing assassinations of prominent anti-Syrian figures and other attacks in recent years, including the 2005 assassination of former Prime Minister Rafik Hariri.
