MEXICO CITY, May 26 (Xinhua) -- A government investigator was killed and three other people were injured on Thursday evening when gunmen attacked a prosecutor's office in the town of Villa Ahumanda, in the northern state of Chihuahua.
The prosecutor-general of Chihuahua said that the attack, which happened at 8:15 p.m., was carried out by a criminal group backed up by municipal police.
Gunmen arrived in trucks outside the prosecutor's office, and opened fire. Agent Edgar Mariano Rojas died as a result of his injuries, while three other investigators were taken to a hospital in nearby Ciudad Juarez.
The statement added that agents had arrested on Friday the director and coordinator of the Ahumada police, under suspicion that they helped the gang carry out the attack, while other police officials are under investigation.
The two policemen, identified as Guillermo C. and Carlos Alberto D., were arrested while travelling in a truck, stolen in October 2016, and had in their possession an assault rifle and two handguns.
"The investigations revealed that the police chiefs of this municipality had links to a criminal group and that, on Thursday night, they acted as vigilantes in the armed attack," explained the statement.
