DENVER -- Three separate sexual assaults in central Denver in the last five days, and one in a neighboring county last month, are connected to one man, police announced Wednesday afternoon.

Police Chief Gerald Whitman identified the suspect in all four cases as Brent J. Brents, 35.

"He should be considered armed and dangerous," Whitman said.

Brents has a record of prior sexual assaults and is wanted on a sexual assault warrant out of Aurora, according to the police chief.

The warrant in Aurora is for sexual assault on an 8-year-old boy, according to Kathleen Walsh of the Aurora Police Department. She said the alleged assault occurred in November 2004.

Police identified Brents as the serial sexual assault suspect, based on DNA evidence.

7NEWS Investigator Tony Kovaleski obtained the full list of sex offenders in Denver and said Brents is not on the list. He is on the sex offender list in Aurora, Kovaleski said. Brents is thought to have lived in Aurora some time ago.

Brents' last known residence was an apartment near 12th Avenue and Washington Street in Capitol Hill. That's near where three of the sexual assaults occurred, Kovaleski said.

The latest assault was reported Monday night at a home near 8th and Vine, when a man armed with a knife entered a home as two girls slipped into their pajamas and their grandmother was putting them to bed, police said.

Authorities said the three were sexually assaulted but did not indicate the specific nature of the attacks.

Last Friday there were two attacks, three hours apart, at 6th and Clarkson and 11th and Adams. They occurred in broad daylight.

One of the victims in the assaults told 7NEWS that keeping these assaults in the spotlight is the first step toward stopping the violence. The woman, whose name will be kept private, said this is the time for the neighborhood to come together and show the attacker that he will not win.

A community meeting was scheduled at Teller Elementary School Wednesday night to inform the neighborhood about what is happening, how they can protect themselves, and how to help police catch the man.

But the woman 7NEWS talked with said it isn't going to stop there. She will be holding a rally at 6th Avenue Pet Supplies -- the same place where she was attacked -- to send a message.

"The store will be here and that we will continue living and that I need to continue living," she said.

She's a strong woman who won't go away quietly.

"I realized that this was an issue so much bigger than myself," she said. "They need to know this violence is not going to be tolerated and that this neighborhood is going to be safe again."

The woman and her friends say they don't know the man who attacked her so they're reaching out to the public to help.

"It has got to stop ... This is both a response to an incident to our friend, but also a more broad statement to say, 'This is intolerable problem in our community and we are not going to stand for it," said the victim's friend, Linda Ronsdell.

The woman's rally on Saturday starts at 2 p.m.

"I have always been a fighter and this is just one other fight that I have to fight and will," the victim said.

The family in Monday night's assault issued a statement saying, "We deeply appreciate the concern of the community for our family. As a family, our priorities are assisting the police with their investigation and healing."

Denver police said more than 100 officers, including FBI agents, are working on this case. The rapidly formed team is one of the largest investigative squads in the city's recent history.

"This is not typical," Whitman said. "You don't see three sex assaults in such a short amount of time and in such close degree. That just doesn't happen."

Solving these assaults is such a priority that the Crimestoppers hotline is being manned 24 hours a day. There is a $2,000 reward leading to the arrest and conviction of Brents.

Anyone with information on Brents is asked to call Crimestoppers at (720) 913-7864.
