A 31-year-old man was charged with felony indecent exposure in King County Superior Court Monday after an incident at a Federal Way apartment complex.

According to court documents, the defendant Ngaira Masika Muhanji, of Covington, confessed to exposing himself to his neighbor.

After being arrested for the April 7 incident, Muhanji also told police that he had exposed himself numerous times before and admitted to molesting a young relative and another underage girl, according to documents.

The Federal Way Police Department is continuing to investigate these claims.

According to charging documents, Muhanji admits that he has sexual urges that he cannot control.

The latest arrest came at an apartment complex on 25th Avenue Southwest in Federal Way. A 28-year-old female went outside onto her balcony to smoke a cigarette and sat down to begin watching a movie on her cell phone, according to charging documents. The woman heard a noise coming from her neighbor’s balcony. When the woman looked over, she observed an unknown black male naked and masturbating, the documents continue.

After getting up from her chair to go back inside, the man was laughing and tried to get the woman’s attention by saying “hey” and “hello,” according to documents. The woman then went inside her apartment and called 911.

Federal Way police responded to the apartment complex, where they knocked on the neighboring apartment’s door. Muhanji answered the door and allowed the officers into the apartment to speak with him, the documents continue. At that time, Mahanji was read his Miranda Rights and asked why he was being arrested.

“Because I exposed myself to the neighbor,” Muhanji told the officers. “The voices in my head told me.”

According to court documents, Muhanji has previously been convicted of indecent exposure in 2011 for an incident associated with a 2009 Seattle Police Department case and receives mental health treatment and normally takes medication as part of his treatment, but had been off of it in recent days.

After being arrested, Muhanji spoke of several previous incidents with Federal Way police. According to documents, Muhanji told an officer that he had recently contacted a 12-year-old female through Facebook with the intent of communicating with her for sex. He stated that he knew the girl was 12 because she is the sister of his friend and he was 20 years old when she was born.

Muhanji admitted that he exposes himself about “once a week” to numerous people, has forced a 5-year-old relative to touch his penis and he molested an inebriated middle school girl eight years ago, according to documents.

Bail in the Federal Way case was set at $150,000.
