Police were called to a California marijuana dispensary on Sunday night (09Feb14) to investigate an alleged dispute involving hip-hop mogul Marion 'Suge' Knight.

Cops attended the scene at the building in Los Angeles following a reported argument between the Death Row Records founder and an employee, according to Tmz.com.

No arrests were made but sources tell the website that police are investigating allegations Knight threatened one of the workers during the bust-up.

Knight was placed on probation in January (14) as part of a plea deal he struck with prosecutors after failing to attend court dates on a charge of driving on a suspended licence.
