Edmonton police are warning the public about a convicted violent sexual offender who is now living in the city.
Denzel Dre Colton Bird, 30, was sentenced to 15 years in prison in 2018 after pleading guilty to aggravated sexual assault for an attack on a woman he didn't know in Lethbridge.
"Based on information available to the Edmonton Police Service, Bird is assessed as presenting a significant risk of harm to members of the community," police said in a warning issued Thursday, Oct. 8.
Police said they weighed Bird's privacy, but decided after "careful deliberation" that the public should know.

The 2016 attack
On the morning of Sept. 30, 2016, a 25-year-old woman was walking to work in Lethbridge before dawn.
According to the facts presented in court, Bird came up behind her, struck her in the head with a metal pipe, dragged her into an alley and sexually assaulted her. He left her there. Two men found her later that morning.
She had life-threatening injuries, including skull fractures and a serious brain injury. She spent about four months in hospital, and had to learn to walk and talk again. In court, her family said she still struggled with her memory and balance.
Her identity is protected by a publication ban.
Caught by DNA, sentenced to 15 years
Lethbridge police arrested Bird in October 2016. They linked him to the attack using DNA evidence, and found the woman's blood on clothing tied to him.
He was originally charged with attempted murder and several other offences. In September 2017, he pleaded guilty to aggravated sexual assault and break and enter. The other charges, including attempted murder, didn't result in convictions.
On June 15, 2018, Judge Jerry LeGrandeur sentenced him to 15 years. The Crown had asked for 20. Bird got credit for time already spent in custody.
His conditions in Edmonton
Bird is on statutory release, supervised by Correctional Service Canada. According to police, his conditions include:
Living at a designated, approved facility.
A curfew from 10 p.m. to 6 a.m.
No alcohol or drugs.
Reporting any relationships with women or girls to his parole supervisor.
Police haven't said where the facility is.
Why he's out after a 15-year sentence
Most people serving federal sentences are released by law after serving two-thirds of their time. That's called statutory release. Unlike parole, it isn't a decision the Parole Board makes, though the board can keep someone in custody past that date if they're considered too dangerous.
It isn't the end of the sentence. Bird stays under supervision, with conditions, until his full 15 years run out. If he breaks his conditions, he can be sent back to prison.
Why police went public
Police don't issue public warnings for every offender who's released. They do it when they believe someone poses a significant risk.
The warning isn't about a new crime. Police haven't said Bird has done anything wrong in Edmonton. It's so people can take reasonable precautions.
Police also asked the public not to take any vigilante action. Harassing or threatening someone under supervision is a crime, and it doesn't make anyone safer.
How to report concerns
If you see Bird breaking his conditions, call the Edmonton Police Service non-emergency line at 780-423-4567, or #377 from a mobile phone. Don't approach him.
If someone is in immediate danger, call 911.
