A suspected school shooter is in custody after opening fire at a middle school and injuring at least two people in Roswell, N.M., according to police.

There were preliminary reports of injury, according to New Mexico State Police, however a spokesman said the extent, including the number of possible victims, was unknown.

Law enforcement sources told ABC News there were two victims in the school shooting. It was not yet known whether they were children or adults.

The Eastern New Mexico Medical Center has confirmed they received two patients. They won’t say their conditions at this time or how old they were.

Students were being bused from the school to Roswell Mall where parents will be allowed to pick up their children, police said. Parents are being asked by authorities to stay away from the school.

The Roswell incident is the latest school shooting to rattle the country. It comes one month after a gunman open fired at Arapahoe High School in Colorado.

Police said Karl Pierson, 18, who was armed with a shotgun, machete and had Molotov cocktails in his backpack, was intent on seeking "revenge" on the school's debate team instructor who had dropped him from the team.

Pierson came upon senior Claire Davis, 17, while looking for his intended target. He critically wounded the high school senior before police said he took his own life.

Davis died on Dec. 21 from her injuries.

The Arapahoe shooting also took place on the eve of the first anniversary of the Sandy Hook school shooting in Newtown, Conn., in which 27 people - most of them first graders - were killed.
