ORCHARD PARK, N.Y. (AP) -Police investigators spent nearly 90 minutes at the Buffalo Bills headquarters Thursday trying to interview players they believe have information about the hit-and-run accident involving running back Marshawn Lynch's SUV.

It was not immediately clear whether investigators actually spoke to any players. Police have also not revealed who those players are or why they were interested in talking to them.

Four police officers visited the Bills, three days after Erie County District Attorney Frank Clark said he was expanding his investigation to focus on the passengers in Lynch's 2008 Porsche Cayenne when it sped off after hitting and injuring a female pedestrian at an intersection early on May 31.

Clark has called Lynch the principal suspect and is acting under the presumption the player was driving during the accident near the city's downtown bar district.

Lynch has declined comment. His attorney, Michael Caffery, did not reveal any information during a brief meeting with prosecutors on Monday.

On Thursday, Caffery said Lynch was not among the players scheduled to be interviewed by police.

Clark was out of the office on Thursday, but an assistant issued a statement declining comment while the investigation is proceeding.

Clark has previously said he's confident charges will be filed, and added he'll impanel a grand jury if necessary to compel witnesses to cooperate. Without going into details, Clark has also said there was more than one person in the SUV at the time of the accident.

The victim, identified as a 27-year-old woman from suburban Toronto, had a bruised hip and a cut that required seven stitches. She was treated and released from a hospital on the same day.

The Bills completed their final day of mandatory minicamps on Thursday after coach Dick Jauron, in what he called a reward for his players, canceled a final session scheduled for Friday. Lynch attended all but one of the team's 15 minicamp sessions this past month. He missed one for corrective eye surgery last week.

Bills spokesman Scott Berchtold declined comment regarding the police visit, other than to say: ``We've cooperated fully and we will continue to cooperate fully with the authorities.''Copyright © 2005 The Associated Press.
