THE owner of the farmhouse under siege wrote a "very strong" solicitor's letter to gardai more than three months ago warning about Mr Isenborger's behaviour.
Mr Michael Hehle, a 55 year old Austrian businessman, complained to gardai in Ballyconnell, Co Cavan, last October according to his solicitor, Mr Gabriel Toolin.
Mr Hehle, who owns the Drumcondra City Wild West style equestrian centre in Ballinamore, Co Leitrim, said he gave Mr Gerrit Isenborger numerous chances to vacate the premises. He obtained an order for possession of the farm house in July 1995.
Mr Hehle, Who lives in Leitrim, says he bought the Bawnboy property in 1992.
Mr Hehle said Mr Isenborger approached him in 1994 looking for a job. Mr Hehle said Mr Isenborger told him he had had previously bought old houses, decorated them and then sold them.
"I was looking for a caretaker for this house and he told me he would be a good caretaker and do all the repairs," said Mr Hehle.
The men agreed verbally that Mr Isenborger would carry out repairs to the windows, roof and doors of the house in return for slaying there rent free, according to Mr Hehle.
"He moved into the house and he didn't do anything. In reality I had to employ a contractor to do the repairs," said Mr Hehle.
Mr Hehle says he paid an electricity bill for Mr Isenborger in 1994 before the account was transferred from his name. He says he was not reimbursed for this by Mr Isenborger.
When he asked Mr Isenborger to leave the house in spring 1995, because he was not fulfilling his contract, Mr Hehle said he was told: I guarantee you that it will be difficult for you to get me out." Mr Hehle then initiated legal proceedings.
He said he did not feel well about yesterday's incident. But I couldn't do anything else because he didn't pay me £1 so I have make some money ... I had no choice. If he would have told me `I am not able to do the job, but I will pay you £20 per week'. But he told me `I will never pay you £1 and you'll never gel me out of here'."
Mr Hehle said he had not allowed Mr Isenborger to have his mother living with him. He said she stayed on and off in the house and moved there permanently in September 1994.
"When I asked `Why his your mother here?', he told me `She has a daughter in France and she is travelling around and it wasn't a big problem to me'.
Last October, Mr Iseborger brought a civil action against Mr Hehle for £30,000 in damages for breach of contract and work and services carried out. Cavan Circuit Court dismissed the claim and it was not appealed.
