The father of star Celtics guard Jaylen Brown has been arrested for attempted murder, multiple outlets reported Thursday.

Quenton M. Brown, a former boxer who goes by his middle name Marselles, was booked Thursday morning on suspicion of attempted murder in connection with a Las Vegas stabbing, NBC affiliate 3 News reported, citing court records.

The alleged stabbing of a youth football coach stemmed from a parking spot dispute, according to TMZ, which noted Brown “doesn’t have a close relationship with his father and was unaware of the arrest or incident.”
