POLICE are hunting a man behind an armed robbery of a chemist store in Toowoomba this morning.

Initial investigations suggest the man armed with a knife entered the Discount Drug Store on Mylne St about 8.15am.

Once inside, the man who was wearing a dark jumper, dark long pants and gloves, threatened staff who handed over cash and a quantity of drugs before fleeing.

He was last seen running from the store down to Russell St where police believe he changed his clothes to a blue singlet, long pants, socks and no shoes.

No-one was physically injured in the robbery.

Police roped off the scene for at least an hour after the incident and customers were blocked from entering the store.
Passers-by were urged to move on from the area as Scenes of Crime officers examined the pharmacy.

The man is described as being Caucasian in appearance, aged in his 20s, with a slim build.

Investigations are continuing, and police have appealed for anyone with information, or who may have seen the man running from Mylne St towards Russell St, to come forward.
