COLORADO SPRINGS, COLO. -- Colorado Springs police have arrested 29-year-old Robert Gray for allegedly sexually assaulting a child, the second time he has been arrested in 2011.

Police began investigating the alleged sexual assault in March when a 9-year-old boy said he was sexually assaulted by a family friend when he was 7 years old.

Gray is a registered sex offender who has lived in Colorado Springs for some time.  His previous arrest was also for sexual assault on a child.

Police said there does not appear to be any other victims, but they are asking anyone with information on Gray to come forward.
