BERLIN (AP) -- Police in southwestern Germany say they're looking for suspects after someone threw an explosive device over the fence of an asylum-seekers' home in the night in the town of Villingen-Schwenningen.
Regional police spokesman Thomas Kalmbach said Friday "it was just luck" the device did not explode and nobody was harmed.
Kalmbach says an unidentified person threw the device toward the home at 1:15 a.m. It was noticed by residents, who quickly notified police. A bomb squad destroyed the device in a controlled explosion on the scene after evacuating the home.
Kalmbach said he can't confirm a dpa news agency report that the device was a hand grenade with the pin removed.
Germany took in nearly 1.1 million asylum-seekers last year and there have been multiple attacks on such residences.
