OMAHA, Neb. (AP) — Omaha police are investigating two bank robberies that happened minutes apart.

Authorities say a man wearing a ski mask and armed with a gun robbed a First National Bank branch about 10 a.m. on Monday. He demanded cash and fled on foot.

About 15 minutes later, a man robbed a Wells Fargo bank a few blocks away. Police say he didn’t show a weapon.

A man matching the robber’s description in the Wells Fargo holdup was taken into custody. Police say 48-year-old Jesus Robles, of Omaha, was arrested for robbery, obstructing a police officer and resisting arrest. Robles’ case is not on the online court system and it’s unclear if he has an attorney.

Police don’t believe the robberies are connected. No injuries were reported
