Policeman arrested over casino arson

Federal police have arrested a state police officer in connection with an arson attack at a casino that killed 52 people in northern Mexico last month.

The officer was caught on a surveillance video sitting in a vehicle outside Casino Royale, presumably connected to the attack, said the Attorney General's regional chief, Jose Cuitlahuac Salinas. Five alleged members of the Zetas drug cartel were arrested on Sunday over the 25 August fire, in which 52 people died. Police are investigating whether the arson attack was in retaliation for the casino not paying extortion money.
