Police are sharing more details about PnB Rock's death a day after the rapper was gunned down at a popular L.A. restaurant.

On Monday, PnB Rock – real name Rakim Hasheem Allen – was shot and killed while eating lunch with his girlfriend Stephanie Sibounheuang at Roscoe's House of Chicken 'N Waffles.

The couple shares a 2-year-old daughter, Xuri. The rapper was also a father to another little girl Milan Allen, 8.

A suspect approached the "Fleek" rapper and ordered him to hand over jewelry and other items. Moments later, the suspect pulled out a gun and shot PnB Rock several times. The rapper, who was 30 years old, died shortly after and the suspect fled in a getaway car.

On Tuesday, Los Angeles Police Chief Michel Moore said it was likely an Instagram post alerted the assailant to the rapper's location, per The Los Angeles Times.

PnB Rock "was with his family — with his girlfriend or some kind of friend of his — and as they're there, enjoying a simple meal, [he] was brutally attacked by an individual who apparently [came] to the location after a social media posting," said Moore, according to The Times.
