Malcom Shabazz died last week from injuries he received after being beaten up near a bar in Mexico City.
Now police say Shabazz and another man were arguing about a bar tab that was said to be $1,200.
The two were at the Palace Club around 3am and the other man says he was robbed but not beaten.
Cops say Shabazz had a blood alcohol level that was three times the US limit for intoxication at the time of the incident.
It appears the club is a center for prostitution and clubs charge men who only talk to the women.
Reports say two women had invited Shabazz and his friend to the bar after meeting them on the street.
