WICHITA (AP) – A Wichita police dog helped end a three-hour standoff that began when a man threatened to blow up a Shell gas station.

Police say the man entered the station about 10 p-m, Tuesday and told the employee he had explosives in his backpack. The employee was able to push the station’s silent alarm before he was released about a half-hour later.

Wichita Police Capt. Jeff Easter said the suspect told police he had C-4 and was going to blow everybody up. About 15 homes around the station were evacuated.

The man stopped responding, a police dog was released into the station. The dog backed the man into a corner, and he was taken into custody.

Police say the suspect’s backpack did not contain any explosives.
