Antonio Velez, 48, of Kings Highway East, has been charged with two counts of risk of injury to a minor, following a complaint from the state Department of Children and Families.

Police received a complaint Jan. 10 that detailed allegations of sexual abuse and improper conduct by Velez to his two minor children while they were visiting him at his home about a month before.

The children do not live in Fairfield, police said.

A warrant was issued for the arrest of Velez, who turned himself in at police headquarters Friday.

He was released on a promise to appear Feb. 22 in Bridgeport Superior Court.
