Coralville Police are investigating a strong-arm robbery of a male and female about 1 p.m. Monday in the 700 block of 1st Avenue.

Police said a male suspect approached the victims, displayed a handgun and demanded money. They said the suspect physically assaulted both victims, and stole a wallet before running south on 1st Avenue.

The victims said the suspect was tall and thin, wearing black pants and a red shirt. They said a mask covered most of his face.

Emergency crews took both victims to a hospital for treatment of minor injuries.

Because the robbery happened close to Central Elementary School, police notified the school which initiated its established protocols.

If you have information about this crime, police ask that you contact Crime Stoppers at 358-TIPS (8477).
