Avondale police have issued a public alert about a registered sex offender who has moved into the city.

Matthew Allen, 33, is living at a home in the 2500 block of South 114th Avenue, east of South Avondale Boulevard and north of West Lower Buckeye Road, police said.

In 2006, Allen was convicted of one count of second-degree sexual abuse out of Deschutes County in Oregon. The 16-year-old female victim was known to him, police said.

Allen is not on probation or parole.

The alert is the result of the Arizona sex offender law that took effect in 1996. The law requires community notification of some sex offenders.

Authorities have classified Allen as a Level III, or high-risk, sex offender, police said.
