(AllHipHop News) Malcolm “Wais P” Byer was once a member of Jay Z’s Roc-A-Fella crew. He appeared on the Hip Hop legend’s “I Should Die” off 1998’s Vol. 2… Hard Knock Life. The 41-year-old Brooklyn native is now facing a single charge of promoting prostitution.

The Wall Street Journal reports Wais was arrested on Wednesday and arraigned on Thursday. He was one of three men that has been indicted on similar charges since December. Authorities claim all four suspects were arrested in connection to an ongoing Midtown prostitution investigation known as “Bright Lights…Big City.”

31-year-old Karmik Grant-Byas, 31-year-old Jamal Mobley, and 40-year-old Christopher Rose are awaiting trail on indictments ranging from sex trafficking to promoting prostitution. Police monitored the alleged pimps through wiretaps and seized financial records.

Wais was placed under investigation starting in 2013, and a Manhattan grand jury indicted him last week. He is currently being held without bail.

Along with Haph, Wais P was one half of the rap group Da Ranjahz. They were part of Jay Z’s Carter Faculty under the Roc-A-Fella umbrella. They never dropped a full album under the company, but the duo did release the independent project Who Feels It Knows in 2003.

“We were there from the beginning. We were there when the Roc was a pebble and the records used to come to Jay’’s house. It’’s bigger than music with us,” Wais told AllHipHop.com in 2007. “I still go to Thanksgiving and Christmas dinners with Jay’’s aunt in Brooklyn. It’’s a family thing.”
