WEST ALLIS, Wis. -- A man was arrested on charges of robbing Guardian Credit Union, 11200 W. Oklahoma Ave., according to West Allis Police.

The incident happened late Tuesday morning.

Police said the man is in custody because he was tackled by a Good Samaritan inside the bank.

No injuries have been reported.

At the top right-hand corner of the screen of the video, you'll see a 54-year-old bank customer waiting for his wife.

While grabbing a bag of popcorn, the 21-year-old robbery suspect, wearing a hooded sweatshirt, walks through the doors.

Seconds later, the suspect with his face covered, hands three tellers a note.

The employees start taking cash out of their drawers. Police say the robber collected $8,000.

That's when the husband who was patiently waiting starts moving toward the accused robber, finally lunging at the masked criminal.

Moments later, the frightened wife is jumping and screaming as her husband wrestles to keep the suspect on the ground.

The suspect has not yet been charged. Police say he has no prior criminal record.
