An explosion in downtown Mexico City near police headquarters on Friday could be a response from organized crime groups to recent drug arrests, said authorities after studying the facts.

Yesterday at 2:32 p.m. the blast roared meters away from offices of the Public Security Secretary of the Federal District. According to sources, police officials and government authorities, the explosion may have been a response from organized crime due to the capture of members of the Sinaloa and Gulf drug cartels on Thursday.

According to the reports, the bomb's detonator could be a man who died in the explosion. A woman who accompanied him is now hospitalized with serious injuries. She will give a declaration to police today, the sources said.

The home-made device eliminated the possibility that the attacks could be from rebels or armed groups, according to police. Instead, they speculate the attack was meant to intimidate police authorities who have seized weapons, drugs and money from gangs in recent months.

Marine Secretary of Mexico, Francisco Saynez stated the federal forces are not afraid to fight the crime and will continue to act against it. He said that while the explosion was isolated, it makes an impact on people's safety.

As a result from the blast, Mexican authorities launched a contingency strategy to patrol 24 hours a day in police cars to guarantee security in strategic locations, related to transport, drinking water and electricity. The plan is being coordinated by the Federal District governor.
