A man was arrested earlier today after he allegedly robbed a Walgreens in south Minneapolis and then fled on a city bus, a police spokesman said.

The suspect, whose name and age have not been released, was being questioned by detectives Monday afternoon after being apprehended a few blocks from the pharmacy, at 4547 Hiawatha Av., the spokesman, John Elder, said.

Elder said the robbery occurred sometime before 3 p.m.. when the suspect held up the pharmacy at gunpoint and fled with an "undisclosed amount of goods."

The suspect reportedly tried to make his getaway by hopping on an eastbound Metro Transit bus, but officers caught up to the bus in the area of E. 46th Street and Minnehaha Avenue and took him into custody, Elder said. Criminal charges are expected against the man.

No further information was immediately available.
