The Loyal hitmaker was accused of punching an opponent during an early morning game at the Palms Casino Resort's Hardwood Suite on Monday (04May15).

Brown was named as the main suspect in the police investigation, but his representative moved quickly to shoot down the claims against his client, insisting an "unruly" and "uninvited" party guest had simply been asked to leave the bash, adding, "Chris was not in an altercation with this person."

Now it appears the alleged victim has had a change of heart about pursuing legal action against the singer after phoning detectives on Tuesday (04May15) to withdraw his complaint, according to TMZ.com.

No explanation was given for the decision, but authorities have since closed the case against Brown.

The news will come as a relief for the star, who completed his probation relating to his 2009 beating of then-girlfriend Rihanna in March (15).
