NEW YORK (AP)  -- A sergeant assigned to New York City's Police Academy has been jailed on $500,000 bond after being charged with sexually preying on a child for six years.

Manhattan prosecutors said Friday that 38-year-old Jaime Katz is charged with criminal sex act and endangering the welfare of a child.

Katz is a 10-year police veteran and a former president of the Gay Officers Action League.

Prosecutor's spokeswoman Jennifer Kushner says the abuse began when the boy was 12.

Kushner says some of the encounters occurred in Katz's Rockland County house and at a relative's home in Bergen County, N.J.

Katz's lawyer, Andrew Quinn, did not immediately return a call for comment.

His next court appearance is May 21.
