A TRURO man who told a police officer: "I'll put your head in a cement mixer" when advised to calm down after being abusive in the early hours, pleaded guilty at Truro Magistrates' Court to using threatening behaviour.
Alison May, for the Crown Prosecution Service, said the police had been alerted by a woman he was with who approached their car in Ferris Town, Truro, waving her arms to them.
She started complaining about a matter and was abusive, then Peter Richard Silverlock, 24, of Lemon Row, Truro, joined in, calling the police officers offensive names and saying: "If you try to arrest me I'll slash you."
He said he had a difficult day and had been unable to take his medication. He had a previous conviction for criminal damage.
Silverlock told the magistrates he was a recovering alcoholic and about to go into rehab for drug misuse. He had been under the influence of drugs that night. He apologised for his language.
He was fined £100 and £20 victim surcharge.
