PHILADELPHIA (CBS) – Police say that a member of the NBA’s Brooklyn Nets and two associates have been questioned in connection with a reported sexual assault that allegedly happened inside a Philadelphia hotel.

According to police, a 21-year-old female filed a complaint alleging that she was sexually assaulted inside the Four Seasons Hotel in Center City at about 4 a.m. Tuesday. The female complainant was taken to a hospital for an examination.

Police sources say Brooklyn Nets power forward/center Andray Blatche, along with two friends, was taken to the Special Victims Unit for questioning.

The Nets were in town to play the 76ers at the Wells Fargo Center Tuesday night. Blatche told reporters Tuesday that he did not know anything about the incident and was only in town to play basketball.

According to sources, Blatche reserved a room for two of his friends, which was separate from the room the Nets supply.

Sources say Blatche and one of friends entered a sixth floor hotel suite with two women they apparently knew.

When they entered the room, sources say the four saw the accuser having sex with the second of Blatche’s two friends in a bedroom. Sources say when the first friend walked out of the bedroom, Blatche’s second friend went into the bedroom and also had sex with the accuser.

After the two were finished, the second friend joined the four others in the living room of the suite while the accuser remained in the bedroom. Moments later, officers knocked on the door and said they had a report of a rape.

All six at the hotel suite, including the accuser, were taken to the Special Victims Unit for questioning.

Sources say at no point during the sexual encounters did anyone hear cries to stop or screams.

Detectives were questioning the accuser Tuesday afternoon and interviewed Blatche’s two friends afterward. Sources say Blatche himself was cooperative with authorities.

Prior to the incident, sources say Blatche and at least one of his friends were at a gentlemen’s club and investigators were looking at the club’s surveillance tape as part of the investigation.

Investigators processed the suite and were checking the hotel’s cameras and phone records.

So far, no charges have been filed.

Blatche posted a tweet on his Twitter page at about 12:15 p.m. that read: “Im ok and I didn’t do anything jus was n the area when it happened”.

By 1:30 p.m., the tweet had been deleted from his account.

The following statement was issued from Brooklyn Nets General Manager Billy King:

“We are aware of the ongoing police investigation regarding a member of the Brooklyn Nets. We will have no further comment until the investigation has concluded. All of our players are available for tonight’s game.”

A representative from the Four Seasons Hotel Philadelphia released the following statement:

“The Philadelphia Police Department responded to a call to Four Seasons Hotel Philadelphia early this morning (January 8). We are fully cooperating with the police investigation. We would advise all questions be directed to the Philadelphia Police Department at 215.686.3388.”
