The Mililani man who allegedly attacked two teenage girls in separate incidents last week made his first appearance in court yesterday.

District Judge Faye Koyanagi set a preliminary hearing for Nicholas Anduha at 1:30 p.m. tomorrow in District Court.

Anduha, 20, appeared in shorts and a T-shirt, with his legs shackled and under the watchful eyes of prison guards.

Anduha is charged with seven counts of first-degree sexual assault, one count of felony kidnapping and one count of third-degree sexual assault.

He waived the reading of his charges and the judge reaffirmed his $500,000 bail.

Anduha is accused of being involved in separate incidents in Mililani on Sept. 16 in which 15-year-old girls told police they were abducted by a male in his late teens or early 20s.

In one incident, the girl said she was kidnapped and sexually assaulted over a 6 1/2-hour period. She said she was walking on Huo Place to a friend's house when a man grabbed her and forced her into a white van shortly before 7 a.m. She told police the man ordered her to lie down on the van's floor as he drove around Wahiawa. He stopped at a park in Wahiawa, where he sexually assaulted her, according to police records.

The man drove to Waimea Bay Beach Park, where he again sexually assaulted her, police said. At about 1:30 p.m., he drove her back to the Mililani area and let her go.

In the other case, a 15-year-old girl said she was walking with her boyfriend at 3:30 a.m. in Mililani when they were confronted by a male with a knife.

Police said the assailant ordered the boyfriend to leave. The man then placed his arm on the girl's shoulder and held the knife to her stomach. The boyfriend confronted the man, who released the girl and drove away, police said.
