LOS ANGELES (AP) - Police say masked men in dark clothing stopped a jewelry merchant in his car, beat him and stole $2 million worth of diamonds during a brazen Los Angeles street heist.
    
Police Lt. Alan Hamilton said Friday the victim told investigators he was driving down a well-lighted North Hollywood street late Thursday when his car was blocked by two vehicles and five to six men jumped out.
    
The men ran up to the merchant's car and smashed a window while struggling for the backpack containing the diamonds. The attackers got back in their vehicles and fled.
    
Police say the victim followed the thieves but lost them in traffic.
    
The merchant was treated and released for minor injuries.
    
No arrests have been made.
