Feltwell man admits posting bombs through letterbox of Boughton Surgery
A man has admitted posting bombs through the letterbox of his doctor's surgery.
Ozzie Welsh, 39, made three explosive devices and planted them at Boughton Surgery, near Downham Market, Norfolk.
He denied he intended to cause an explosion which would endanger life or cause serious damage.
The Old Bailey heard Welsh had a history of self-harming at "the extreme end". He was remanded in custody ahead of sentencing on 13 March.
On the first day of his trial, Welsh, of Short Lane, Feltwell, admitted having an explosive substance, making the devices and posting them through the letterbox on 27 January 2016.
He pleaded not guilty to doing an act with intent to cause an explosion. The charge will lie on court file.
The court heard when police searched Welsh's home, they uncovered a stash of chemicals which could be used to make bombs.
He had made the devices months before and had been spoken to by police about setting off explosions in his garden in the past, it was heard.
The court heard there were concerns about Welsh's mental state and he had been in dispute with doctors before the incident.
Judge Mark Lucraft QC ordered two reports - one psychiatric and the other from the probation service on Welsh's potential dangerousness - ahead of sentencing.
