The city's police commissioner says that a police officer acted appropriately when using a stun gun on a Philadelphia Phillies fan who jumped onto the field.

The Philadelphia Inquirer has reported that Commissioner Charles Ramsey, speaking Tuesday to KYW Radio, said the officer "acted appropriately" when he fired a Taser to subdue a 17-year-old male fan who had run onto the field Monday night at Citizens Bank Park.

Ramsey said, "It was inappropriate for him to be out there on the field. Unless I read something to the contrary, that officer acted appropriately. I support him 100 percent."

It was reported that video showed the fan running around on the outfield, eluding several slow-footed security personnel before a Philadelphia officer drew his Taser and shot it into the teen's back. The youngster immediately fell to the ground, and after a few minutes got up and was escorted off the field under his own power.

The teen was charged as a juvenile with resisting arrest, disorderly conduct and defiant trespass, and was released to his parents Tuesday morning, the Inquirer further said.

The officer's action has created controversy over the appropriate use of force and if stun guns should be used in such situations, especially on juveniles. But Ramsey told KYW the officer had no way of knowing the fan's age.

Phillies spokeswoman Bonnie Clark said, "This is the first time that a Taser has been used by Philadelphia police to apprehend a field jumper. The Police Department is investigating this matter and the Phillies are discussing with them whether in future situations this is an appropriate use of force under these circumstances. That decision will be made public."

The Inquirer further added that running on the field during a game has been a crime for decades, but suspects are usually wrestled to the ground and arrested. (With Inputs from Agencies)
