Two men tried to rob a woman walking in Waterloo’s university district Friday morning, police say.

Waterloo Regional Police were called to the area of Hickory and Hazel streets around 1:15 a.m.

They say the men had asked the woman to use her cell phone, which she refused.

After that, one of the men allegedly pulled out a knife and ordered her to give them everything she had.

Police say the men left the area without stealing anything after the woman started to scream.

The men are described as being black and in their early 20s, with average builds. One was said to have a bald or shaved head and be wearing a red T-shirt and black shorts, while the other was seen wearing a white hoodie and black pants.
