A 28-year-old Hercules man police suspect of at least one in a series of sexual battery assaults on women joggers using the Iron Horse Trail in Walnut Creek has surrendered to Regional Park Police.
The man, who was not immediately identified, surrendered to investigators after a warrant was apparently issued for his arrest.
A photo of the alleged assailant, taken after one of the attacks, was released by park district police in an effort to identify the suspect. It was not immediately known if the photo was of the man arrested Wednesday.
Decided to head off the knock at the door.
