Police say two men accused of an armed robbery in Ohio were arrested after taking a Greyhound bus back to Detroit.

Michigan State Police said Cleveland police contacted them Thursday saying two people had robbed a pharmacy at gunpoint and then boarded the bus for Detroit with a black duffle bag and gray backpack.

The two suspects were arrested at the Greyhound bus terminal and police said they found evidence from the robbery.

Police said the suspects told them they had ditched the weapon in Ohio.

The suspects are a 21-year-old and 17-year-old from Detroit.

The two are expected to be extradited back to Ohio to face charges.

In addition, police said the 17-year-old is also a suspect in a separate criminal sexual conduct case.
