Video has emerged of a man being Tasered after jumping on a disabled woman's car and reportedly threatening to cut off a police dog's head with garden shears.
Jamie Swann, 28, attacked Jane Green's car as it sat on her Nottingham driveway in the early hours of October 14.
CCTV shows Swann standing on the roof gesturing wildly with the shears as police try to talk him down.
Officers eventually floor Swann with an electric stun gun, sending him tumbling off the car with the shears flying out of his hand.
Ms Green, 59, said she was "petrified" by the incident, according to the Nottingham Post.
The retired medical secretary, who suffers with a chronic pain syndrome, said she thought Swann was going to break into her house.
"The man was totally unknown to me and he was shouting about guns and waving around my garden shears which he picked up," Ms Green told the Nottingham Post.
Despite her concerns, the video shows her bravely creeping past Swann to unlock her gate.
"I didn't want to be locked in with him," she said. "So I ran past him to unlock it for the police."
Swann later pleaded guilty to causing criminal damage and using threatening words and behaviour to cause alarm or distress.
He was jailed for 22 months, which included 18 months for breaching a previous suspended sentence for theft and burglary.
