A man who made a hoax bomb threat and attacked police officers has been jailed.
Ian Hendrie, of Dartford, hid harmless devices in bins outside his home in what police described as a "cry for help."
The 55-year-old has been jailed for 22 months after pleading guilty to five counts of assaulting a police officer and two counts of criminal damage.
Hendrie left six glass bottles filled with screws and nails in the bins, and told a social worker he had built a number of bombs.
When officers attended his flat in October last year they found the bottles, and realised they contained no explosives.
Hendrie was arrested and taken to a local hospital by officers who were concerned for his welfare.
Once there he became agitated and attacked those around him, and on arrival in custody he damaged his cell and assaulted officers.
Investigating officer Detective Constable Shona Ross said: "Hendrie claimed to have made bombs, hoping the information would be passed to Kent Police.
"When officers attended his address he directed them to the bottles, at no point did they present a danger to the public.
"Upon arrest, he admitted it was a cry of help and that he didn’t fully appreciate the seriousness of his claim or the consequences.
"Hoax reports are a waste of police time and divert resources away from people who genuinely need help. In short, don’t do it."
