Police are calling on women who may be missing undergarments in Melbourne's north to come forward after a man was allegedly found with an abundance of wet bras, believed to have been freshly picked from the clothesline, in the area on Monday morning.

Officers were patrolling Capp Street in Reservoir about 2.15am when they saw a 28-year-old man riding a bike.

They asked him to stop and later arrested him over a number of outstanding warrants.

Police also said they found the man to be in possession of "a plethora of women's underpants and bras - many of which were wet as though they had been hung on a line to dry".

The 28-year-old Reservoir man has been bailed to Heidelberg Magistrates' Court on November 7 in relation to the warrants.

But police also wish to speak to anyone in the Reservoir area who may be missing some undergarments.

Anyone with information should contact Crime Stoppers on 1800 333 000.
