SLIPPERY ROCK — Felony sex assault charges against a Pittsburgh man were dropped Wednesday in a deal that saw him waive a preliminary hearing on a remaining misdemeanor charge.

Samuel K. Njuguna, 25, was facing one felony charge each of rape and aggravated indecent assault, as well as a misdemeanor charge of indecent assault, after state police accused him of raping a woman he met on a dating website.

Wednesday’s agreement between Butler County Assistant District Attorney Russ Karl and Njuguna’s attorney, public defender Joe Smith, also included District Judge Bill Fagley reducing Njuguna’s bond from $75,000 monetary to $25,000 surety bond, meaning he can use a bail bondsman to secure his release.

Njuguna, who has been at Butler County Prison since his arrest in late August, did not post bond Wednesday.

State police charged Njuguna, who is from Nigeria and in the United States on a student visa while attending La Roche College in Pittsburgh, after a Slippery Rock Township woman said he raped her on Aug. 28 after the two met on the OKCupid website and agreed to meet at her apartment.

According to court documents, the woman told police that she told Njuguna she did not want to have sex before the two went into her apartment, where they watched television and had a consensual sex act.

The woman said Njuguna then became “aggressive,” held her arms and raped her.

Karl refused to comment on the deal or the status of the case.

Smith said that the accuser was prepared to testify, but was spared a court appearance as part of the deal.

Njuguna now faces a single misdemeanor charge of indecent assault. Smith said he expects to take that charge to trial.
