An officer's call for backup after seeing what he thought was a gun in a suspect's car prompted a large law enforcement response on Interstate 5 Monday night.
At 8:40 p.m., the officer tried to pull car over for speeding on the freeway near E Street in Chula Vista.
As the officer walked up to the vehicle, he saw what looked like a gun sitting between the suspect's seats.
When the suspect refused to cooperate, the officer called for backup, sending several units from multiple agencies to his aid.
Together, the police got the suspect out of his car, on the ground and in handcuffs.
Officers soon discovered the firearm was a BB gun, not a real weapon.
The freeway was closed briefly as officers investigated the scene.
