Rapper Sean “Diddy” Combs says there is “no excuse” for his behaviour on a CCTV video that has emerged showing him allegedly assaulting his former partner in a hotel hallway in 2016.

Mr Combs released a video apology on Instagram on Sunday night, local time, in response to the video, which was obtained by American network CNN. 

It shows his ex-partner, singer Cassie Ventura, walking down a hotel hallway before he is seen running toward her wrapped in a towel.

He then appears to grab her and violently throw her to the ground, kicking her twice and dragging her along the floor.

“It’s so difficult to reflect on the darkest times of your life, but sometimes you gotta do that,” he said.

“I take full responsibility for my actions in that video … I was disgusted when I did it, I’m disgusted now.

“I’m so sorry, but I’m committed to be a better man each and every day, I’m not asking for forgiveness, I’m truly sorry.”

Mr Combs said he had since sought out therapy and attended rehab
