Man charged with sex assaults on boys

A 31-year-old man from NSW's Hunter region has been charged with sexually abusing two young boys.

Police say the man was arrested on Tuesday following investigations into alleged sexual assaults on the two boys by a relative between 1994 and 2010.

The State Crime Command's Child Abuse Squad launched an investigation last year after a nine-year-old boy disclosed he had been sexually assaulted by a relative on two separate occasions.

It's alleged the boy, who is cognitively impaired, was assaulted at a property in Sydney's northwest on two dates in 2010 when he was seven years old.

During the investigation, detectives identified another person who had allegedly been sexually assaulted by the man.

Between 1994 and 1995, a five-year-old boy was allegedly sexually assaulted by a teenage relative at a property in the greater Lake Macquarie area.

Police say the boy was again allegedly sexually and indecently assaulted by the relative on a number of occasions at another property in the greater Lake Macquarie area between 2000 and 2002.

The boy was aged between 10 and 12 years old at the time of the alleged assaults.

The 31-year-old man has been refused bail and will appear in Raymond Terrace Local Court on Wednesday.

He is charged with four counts of sexual intercourse with a person under 10, four counts of aggravated indecent assault with a person under 16, five counts of sexual intercourse with a person between 10 and 14 years, and one count of indecent assault with a person under 10.
