MADISON, Wis. -

Madison police said they are investigating an attempted robbery at a Walgreens pharmacy on the city's far east side.

Police responded to the Walgreens at 4518 Cottage Grove Road at about 11:35 a.m. Monday after a masked man tried to rob the pharmacy of Oxycontin, according to a Madison Police Department incident report.

A pharmacist said the man passed a note demanding the prescription narcotic and made a threatening statement, according to the incident report.
