PHOENIX (AP) - Police say they've arrested a man in connection with a series of explosions heard in several neighborhoods in northwest Phoenix over a three-month span late last year.
At a news conference Monday afternoon, police officials announced that 44-year-old Houston Willis was taken into custody at his home after investigators developed probable cause.
It's unclear if Willis has a lawyer yet.
Police say they received a tip from the public that eventually led Willis being identified as a suspect.
The explosions started last October and were generally in the area between Thunderbird Road and Union Hills and 27th to 43rd avenues.
Police say they received more than 150 calls in connection to the incidents that mainly caused damage to landscape and property.
It's unclear what kind of explosive materials were used.
