A Lake Jackson bank is open for business after an explosive device damaged a drive-thru teller's window.
Police say nobody got into the bank and no money was stolen. No alarms went off.
The bank was empty at the time of the explosion around 1 a.m. Monday. A customer who stopped to use the night deposit slot noticed a hole in the window before the bank opened.
Lt. Rick Park says a motive for the blast is sought. Park says pieces of the explosive indicate it might have been a homemade pipe bomb.
Bank executive Mike Golden says the FBI does not believe the case involves a terrorist incident.
Lake Jackson is 50 miles south of Houston.
