A bold, midday sexual assault appears to be connected to three other cases within the past two weeks.
A fourth woman has now reported a serial groper matching the same description and pattern, Denver police said.
The most recent case happened on Sept. 4 around 12:20 p.m.
Police said a woman was walking west on Kentucky Avenue between Gilpin and Franklin streets when she passed the man, who was standing in the mouth of the alley.
As the victim passed, the man approached from behind and fondled her, police said.
Police said the victim described the man as being in his early-to-mid 30s . He was wearing a white T-shirt.
The woman said after she was groped, the man drove away in a black Nissan sedan with tinted windows and shiny rims. The sedan may have been an Altima or Maxima model, police said.
Police said the incident matches three other groping incidents.
The first two assaults occurred within just a few minutes on Aug. 21. Police said one woman was fondled while walking in the area of 5th Avenue and High Street
The second woman reported the man grabbed her buttocks in the area of Fourth Avenue and High Street.
Both victims reportedly told police that the man had been parked in the alley, as if waiting for them to pass.
On that day, both described him as a Hispanic male between the ages of 20 and 30. He was wearing a baggy white T-shirt, long baggy shorts and a long belt.
Police say the third assault occurred on Aug. 28 at approximately 7 p.m.
That victim reported she was grabbed by a man at the opening of the alley between Newton St. and Osceola Street on W. 37th Street Police said she described the man as wearing a blue tank top and black pants.
"If we have the suspect out, we want to get him," said detective Raquel Lopez of DPD. "Nobody else has come forward so we're not sure if anybody else has been approached by this male, but this is why we want to get this out to the community."
Anyone with information about this case is asked to call Crime Stoppers at 719-913-7867.
