The Bellevue Police Department is investigating an allegation of assault and personal property damage involving Seahawks running back Marshawn Lynch, said to have occurred early Sunday morning.

The BPD reported that a female alleged the suspect was “Marshawn T. Lynch’’ and that no domestic violence or sexual assault was involved in the allegation. Marshawn Lynch’s middle name is Terrell.

The department said the case has been assigned to a detective and is an active investigation. It reported receiving the allegation at 2:20 p.m. Sunday, with the incident alleged to have occurred at 2:30 a.m. Sunday.

Part of the investigation will include talking to Lynch, said BPD spokesman Seth Tyler.

“We will be reaching out to him yes, absolutely,’’ Tyler said, adding he did not know when that would occur.

Tyler reiterated, “This is only an allegation. We haven’t even verified that he was involved.’’

Tyler said there is no timetable for when there will be any additional information concerning the case.

A Seahawks spokesman said the team had no comment.

The Seahawks practiced Sunday at the Virginia Mason Athletic Center and Lynch participated, having what coach Pete Carroll said later was “a very good practice.’’

The Seahawks did not practice Monday but will Tuesday morning in the final workout of training camp that is open to the public.

Lynch, 28, held out the first week of Seattle’s training camp before returning after the team agreed to turn $1.5 million in incentives and future pay into base salary for the 2014 season. That raised his base salary for this year from $5 million to $6.5 million in the third year of a four-year contract signed in spring 2012 that could be worth up to $31 million.

Last February, Lynch agreed to plead to a lesser charge of reckless driving in his native Oakland, Calif., to resolve a DUI case that dated to July 2012. Lynch was sentenced to two years probation as well as a $1,080 fine.

At that time, Lynch’s lawyer, Ivan Golde, said he was confident Lynch would not be suspended for the incident by the NFL, though the league was expected to review the details of the case. It’s unclear if that has occurred. Lynch was suspended for three games in 2009 when he was with Buffalo after pleading guilty to a misdemeanor gun charge.
