MEXICO CITY (AP) - Mexico City's police chief says a fourth officer has been arrested in the investigation into the kidnapping and killing of 12 young people who disappeared in May from an after-hours bar and later turned up in a mass grave.
Security Chief Jesus Rodriguez Almeida says the four have been turned over to the prosecutor's office and he has no evidence to conclude they were involved.
The Mexico City prosecutor announced Monday that two more police had been arrested in the case, putting the total at three officers. Rodriguez on Tuesday confirmed the arrest of the fourth officer to The Associated Press.
Eighteen people have been arrested so far in the case involving the after-hours bar, Heaven. The killings shook Mexico City's image as a haven from drug-related, organized crime.
