A Suffolk man who threatened a door supervisor at a music festival with a blade attached to a credit card has been jailed for 19 months.

The door supervisor was standing behind a security fence restricting access to the performers’ area at a music event on Peas Hill, Haverhill, when Alexander Hockett jumped on to a wall and tried to get over the security barrier, Ipswich Crown Court heard.

Hockett appeared intoxicated and when the doorman put his hand up to stop him entering Hockett had swung his arm at him, said Peter Gair, prosecuting.

The door supervisor moved his head to avoid being struck and pushed Hockett away.

Other people in the area saw Hockett was holding a blade attached to a credit card which he then used to make slashing motions towards the door supervisor.

A member of the public grabbed hold of Hockett and pushed him away and shortly afterwards Hockett approached the door supervisor and offered to shake his hand.

The door supervisor refused and later Hockett had lunged at him from behind saying: “This is my town. This is my town.”

Hockett was holding the blade on the credit card in his left hand and when he heard the police were on their way he had run off, said Mr Gair.

Hockett had taken off his trousers and following his arrest police officers went to a nearby property and found the credit card blade in his trousers.

Hockett appeared under the influence of something and told officers he had “overdosed”.

While Hockett was being dealt with by police he had struggled and made threats to officers, including spitting at them.

He had also assaulted a police sergeant causing swelling round his left eye.

Hockett, 37, of Evergreen Lane, Great Bradley, admitted threatening the door supervisor with a blade and assaulting a police officer by beating on August 5.

The court heard that Hockett had 131 previous convictions.

Phillip Farr, for Hockett, said his client couldn’t explain why he behaved in the way he did as he had not used Class A drugs for a couple of years and had only had a small amount to drink on the night in question.

He said Hockett was ashamed of his behaviour towards the police and wished to apologise.
