Some of the similarities in the cases brought against Sean “Diddy” Combs this week and Robert Sylvester Kelly several years ago are evident at a glance: Both are world famous, powerful and influential musicians who were accused of sex crimes by federal prosecutors in New York City.

The arrest comes as the music mogul faces deepening legal trouble, including a human trafficking investigation.

Sean “Diddy” Combs was arrested Monday, the U.S. Attorney’s Office in New York City said. Combs was arrested at the Park Hyatt hotel on West 57th Street, a representative said. He was caught off-guard by the apprehension, according to a person familiar with the situation, who added he had been living at the hotel for several weeks.
