The Hip Hop police never sleep. While former drug dealers-turned-rappers cavort onstage flashing the products of their ill-gotten wealth, the feds are meticulously gathering evidence against them.

According to The Sun, British police arrested Jay Z associate Chris Nathaniel, 39, and charged him with the stabbing of Danny O’Shea, 18, in East London.

The police nabbed Nathaniel yesterday when he landed at London’s Heathrow airport on an international flight from the United States.

The entertainment guru — linked with a host of sports idols, showbiz stars and leading politicians — was held with a pal aged 33.

Both were quizzed over the killing of Danny O’Shea, who was stabbed in the neck after being chased by a gang for 300 yards.

The teenager bled to death outside his mum’s home in Canning Town, East London.

Nathaniel was instrumental in brokering a business deal to open a London branch of the “Throne” rapper’s 40/40 restaurant and bar franchise.
