Denver police want to get the word out in hopes of preventing it from happening again.

Around 11 p.m. Tuesday, police say a woman was walking on West Walsh Place near South Federal Boulevard when a man in a maroon Cadillac drove up, grabbed her and tried to drag her into his car. The woman had a knife in her purse and stabbed the attacker before breaking free.

Eight blocks away, just after 12:30 a.m. Wednesday, another woman was knocked to the ground when a man hit her in the back of the head. She was also able to escape.

In both cases the suspect is described at Hispanic, about 6 feet 1 inch tall and weighing about 200 pounds with a long, black ponytail. In the first case, the suspect was described as having a thin beard.

Police believe the cases could be related. Anyone with information should contact Crime Stoppers at 720-913-STOP. You may be eligible for a reward.
