7-Eleven robbed twice in one week

Police are investigating the robbery of a Nanakuli convenience store.

Police said a juvenile male entered 7-Eleven shortly before 2:30 a.m. Wednesday and displayed an unspecified dangerous instrument. He demanded property and fled on foot with the stolen merchandise.

The same 7-Eleven was robbed two days prior.

Police said a man took items from the store about 1 a.m. Monday without paying for the merchandise.

When confronted by a store clerk, the man allegedly pulled a pistol from his backpack and pointed it at the clerk before fleeing.

There have been no arrests yet in the robberies.
