Sean “Diddy” Combs was reportedly taken from his jail cell in New York to a hospital in the middle of the night for an MRI.

According to the New York Post, sources indicated that the 55-year-old rapper, currently held at the Metropolitan Detention Center while awaiting trial on sex trafficking charges, was transported to Brooklyn Hospital Center around 10 p.m. on Thursday.

Page Six later confirmed that the transport was conducted after dark to avoid drawing attention from other inmates or prison staff. An unnamed source mentioned that Diddy was experiencing knee pain and needed to have it examined by medical professionals.

“Combs did not stay overnight at the hospital and returned to his cell within a few hours,” Page Six reported.

An MRI, or magnetic resonance imaging, is described by the National Institute of Biomedical Imaging and Bioengineering as “a non-invasive imaging technology that produces detailed three-dimensional anatomical images,” useful for detecting diseases, diagnosing conditions, and monitoring treatment.

Diddy has stated his commitment to self-improvement, saying, “I’m committed to being a better man each and every day. I’m not asking for forgiveness.”

At the same time, the Los Angeles County District Attorney’s Office acknowledged the disturbing footage related to the case, noting that while they find the images difficult to watch, there is little they can do about it.

Federal authorities have raided at least two of Diddy’s properties as he faces multiple allegations, including sex trafficking and sexual assault. The founder of Bad Boy Records and three-time Grammy winner has previously denied all accusations against him.
