MEXICO CITY , Mexico ( CNN ) -- Mexican authorities deployed more than 1,000 additional police officers to reinforce security at the capital 's 175 subway stations on Saturday , a day after a shooting inside a station left two people dead and eight injured at the height of evening rush hour . Camera footage shows Luis Felipe Hernandez Castillo brandishing a gun . The shooting at the Balderas station in central Mexico City happened after police stopped Luis Felipe Hernandez Castillo , 38 , from writing graffiti on the wall of one of the subway platforms . Five of the injured suffered gunshot wounds , and three others were hurt by the stampeding crowds , officials said . Hernandez Castillo was writing `` Este gobierno de criminales , '' or `` this government of criminals , '' Mexico City district attorney Miguel Angel Mancera said . As police tried to stop him , Hernandez Castillo drew a .38 special handgun and began firing . Mancera said his first impression of Hernandez Castillo is that he may suffer from mental illness . `` One moment he is talking about global warming and then about the message of the Bible and suddenly he focuses on some government , '' Mancera said . Authorities identified Hernandez Castillo as an agriculturalist from the state of Jalisco . Hernandez Castillo also told investigators that he believed a great famine would come , and he traveled to Mexico City to relay a message , Mancera said . Earlier this month , a Bolivian pastor hijacked a passenger jet in Mexico City with a fake bomb , claiming that he acted on a divine revelation to warn people of a forthcoming earthquake . Mancera said Hernandez Castillo was aware of the hijacking , but that the two events were not connected . Hernandez Castillo said he opened fire because he saw the police as a threat to his task of writing on the wall , Mancera said . Preliminary tests show that Hernandez Castillo was not under the influence of alcohol or drugs during the incident , Mancera said . The Mexican government on Saturday posted security camera footage of the shooting . It shows a busy subway platform as the train pulls into the station just before 5:15 p.m. Friday . As the train comes to a stop , there is a disturbance in the crowd , and Hernandez Castillo is seen shooting at an officer . Watch the dramatic incident unfold » . The crowd disperses , and the officer runs out of view of the camera . The officer , who was a bank policeman , is later seen on the footage lying dead , face down on the platform . Authorities identified the officer as Victor Manuel Miranda Martinez . The footage shows a man in a white shirt running off the train and trying to wrestle Hernandez Castillo . The man chases Hernandez Castillo around the platform . He frequently falls either because he slips or is trying to avoid being shot . The man is on the floor facing Hernandez Castillo , about to get up and try to grab him , when he is shot in the head and falls to the ground . Mancera initially said the man was a federal security agent in plain clothes , but later clarified that the man was a civilian , a 58-year-old construction worker . A scattered handful of people remain on the subway platform during the shooting . Some stay on the train . Others walk on the platform very close to the shooter , seemingly undisturbed . Seven minutes later , the camera pans out to show the construction worker lying on his back and the bank police officer in the foreground . Hernandez Castillo remains on the train , occasionally firing his gun and peeking out of the train . At 5:23 p.m. , the camera shows first one , then two , then three plain-clothes police getting into position on the platform . Within moments they rush Hernandez Castillo and pull him out of the train , with nearly a dozen police officers then wrestling him to the ground . Hernandez Castillo was treated at a hospital for a bullet wound to the right shoulder before being transferred to the local attorney general 's office , a common place to hold prisoners during preliminary investigations , a spokesman for the attorney general said . He faces two counts of murder and one count each of attempted murder , aggression , resisting arrest and disturbing the peace , said the spokesman , who declined to be named because he is not authorized to speak to the press . CNN 's Esprit Smith in Atlanta , Georgia , contributed to this report .
