SILVER SPRING, Md. (WUSA9) --A teacher charged for unwanted physical contact with three co-workers has been released on his own recognizance, according to Montgomery County State's Attorney's Office authorities.

Walter Stafon Bowman, 37, a science teacher at the Briggs Chaney Middle School located at 1901 Rainbow Drive in Silver Spring, has been charged with three counts of second degree assault for unwanted physical contact with three co-workers. He was also charged with one count of false imprisonment.

Officials started investigating this case on January 6 when they were made aware of reports of three female co-workers who were allegedly assaulted by Bowman. The first victim reported the incident in August 2013. She said she was sitting in an office with her back to the door when Bowman came unannounced and placed his hands on her shoulders. During another incident with the same victim, Bowman hugged her and began to laugh. The victim was able to break free and started screaming, police said.

Officials say the second victim was allegedly assaulted in a classroom in September when Bowman was crouched on the floor, laughing and touched her ankle. The third victim said Bowman grabbed her around the waist while he was laughing. This incident also happened in September 2013.

Officials believe there may be more victims. If you have any information to report, call police at 240-773-5530.
