DENVER (CBS4)- Three more men have been attacked and robbed in Denver’s Capitol Hill neighborhood. The men were assaulted by a group of eight to ten men on Thursday night near 14th and Humboldt.

The attack follows two similar attacks Tuesday night at 10th and Grant and 11th and Corona. Police believe there could be as many as ten cases of assault in the Capitol Hill neighborhood this month.

Detectives are asking taxi drivers to help look for the assailants. Officers believe it’s important to have an extra set of eyes on the streets.

“Several victims have been robbed and assaulted with baseball bats,” said Metro Taxi spokesman Larry Stevenson. “The suspects are four to five black males, 18 to 21 years of age.”

Taxis On Patrol, or TOP, was set up as a partnership between Denver metro area taxi drivers and police in January. An alert about the crime and suspects goes out to all the drivers.

“That taxi cab is a ticket to the greatest show on Earth. They see everything,” said Stevenson. “We teach them how to look for suspicious incidents, suspicious crimes, suspicious people.”

“This is unconscionable that it’s happening and we’re not going to tolerate it,” said Denver Police Department spokesman Sonny Jackson.

In the past month, police said there have been ten attacks all in or around the Capitol Hill neighborhood. In every attack, at least one person has been hurt.

“The problem is the time of day, basically during the closing bar time crowd,” said Jackson. “They’re preying on people they feel like they can intimidate and take advantage of.”

Several suspects have been arrested, but police believe there are more. The suspects are described as a group of black men and women in their late teens and early 20s. In some cases, they carry baseball bats.
