Sean 'Diddy' Combs is expected to face a third alleged victim on the stand during his trafficking and racketeering trial in New York City.

The trial took a dramatic turn this week as a security guard testified that he took $100,000 to bury footage that showed Diddy viciously attacking his longtime girlfriend Cassie in a hotel hallway in 2016.

Prosecutors have made the footage of Combs kicking, beating and dragging Cassie at the Intercontinental Hotel in Los Angeles a centerpiece of their federal case against him.

They contend it supports the claims of three women, including Cassie, who allege the Bad Boy Records founder sexually and physically abused them over two decades.

Tuesday's testimony comes after that of Diddy's former assistant and alleged victim Mia, who followed Cassie as the second of three key prosecution witnesses.
