Man Arrested for Sexually Assaulting Child at Park 

Posted on by

Franconia Police District- A 42-year-old man is facing charges after sexually assaulting a juvenile at Lake Accotink Park, 7500 Accotink Park Road. Officers were called to the park on May 21 for a report of an assault. The victim was on the playground around 6 p.m. when a man approached the victim, engaged in conversation then unlawfully touched the victim’s thigh. The victim left the play area to avoid the man. Later, the man followed the victim into the water where he unlawfully touched her again. The victim advised family members of the assault. When family members confronted the man, the suspect got into a vehicle and left the area. The family provided information to identify the man from cell phone footage and the vehicle’s registration that he left in. 

Detectives from our Major Crimes Bureau immediately assumed the investigation and obtained a warrant for aggravated sexual battery. Detectives from our Fugitive Track and Apprehension Unit along with the U.S. Marshals Service began tracking Louis C. Allen, of Lorton, after the issuance of the warrant and arrested him on May 24. Three additional outstanding warrants were served on Allen. The warrants included two counts of failure to appear and one count of simple assault against a family member. Allen was taken to the Adult Detention Center where he was held without bond.

Victim advocates from our Major Crimes Bureau’s Victim Services Division have been assigned to this case to ensure the victim’s family is receiving appropriate resources and assistance.
