Austin serial bomber killed himself with explosive device: Police

HOUSTON: A 24-year-old suspected "serial bomber" who terrorised the US state of Texas, especially its capital Austin, for nearly three weeks with parcel bombs is dead after he blew himself up in his car as authorities closed in, police said on Wednesday. Austin has been on edge amid the attacks, which have led to the deployment of hundreds of police officers to the city.Since the bombings started on March 2, investigators frantically searched for clues, calling the attacks the work of a "serial bomber" who increasingly changed tactics.Two people were killed and six others injured in five bombings, terrorising the Texan capital with fear for 19 days.The suspect, identified only as a 24-year-old white man, was killed after detonating a device when officers approached his car off a highway in the city of Round Rock, north of the state capital.The incident follows four bomb attacks in Austin, the state capital, and one in Schertz, 104km south.
