This is the dramatic moment an alleged child snatcher was arrested after an armed teacher stopped him abducting an 11 year-old girl from a school playground.

Ira Cox-Berry, 41, was filmed being cuffed and put into a police car in Ogden, Utah, after Tuesday's alleged abduction, which police say was foiled by a hero teacher at Lincoln Elementary School, which his alleged victim attends.

Cox-Berry is said to have attempted to yank the girl away from the playground during recess, only for the armed employee to shout at him to leave her alone.

When the 41-year-old let the schoolgirl go, the teacher ushered her and 19 other students into a nearby classroom, Ogden City Police Department said in a statement.

After the children were inside the school, Cox-Berry approached the school building and began punching the window in an attempt to force his way inside.

That was when the teacher, who has a concealed-weapons permit, pulled out his gun and held off the 41-year-old while he called 911.

DailyMail.com spoke to the teacher involved on Thursday afternoon. He asked not to be identified over fears for his future career prospects.

But Lt Brian Eynon of Ogden City PD told ABC4 that the teacher was a 'hero,' whose actions were covered by the law.

He said: 'This employee is protected under the Second Amendment. He followed all policy and procedure at the school, and in this particular case, did everything that he should have done to protect the innocent lives of the children at the school.

'And in this case, it is likely that a life was saved or injury to a life was prevented due to the actions of this heroic employee.' Enynon added.
