An explosive device wrapped in a newspaper exploded in a residential neighborhood in Vacaville on Sunday, seriously injuring a man and forcing the evacuation of more than a dozen homes.

The explosion on Cashel Circle occurred about 10:20 a.m. when the unidentified man went to his driveway to retrieve the Sunday paper, said Mark Mazzaferro, a spokesman for the city, about midway between San Francisco and Sacramento.

The man was airlifted to a local hospital and his condition was unknown, Mazzaferro said. It was unclear whether the victim was targeted or whether it was a random attack. There was also no information on the type of device used.

Authorities evacuated 12 to 14 homes in the surrounding cul-de-sac, while investigators from the FBI, the Bureau of Alcohol, Tobacco and Firearms and Explosives and a bomb squad from nearby Travis Air Force Base searched for more explosives.



Police detectives were also canvassing the community for information on anyone acting suspiciously Saturday night or Sunday morning, Mazzaferro said. Residents within a one-mile radius of the explosion were advised not to approach any suspicious packages.
