A 70-year-old man admitted throwing a corrosive liquid at police during a seven-hour stand-off. James Dallas pleaded guilty in Supreme Court yesterday to four counts of throwing a corrosive fluid with intent to resist arrest.He also admitted trespass and using threatening language. The court heard Dallas was found on the premises of the old prison service headquarters on Happy Valley Road, in Pembroke on March 28. He refused to leave when ordered by police and threw a liquid through a window at several officers. Dallas barricaded himself inside and said: “I will kill any police that tries to enter the building. Someone will die today.” Police forced their way into the building several hours later after negotiations with Dallas collapsed. Dallas again threw liquid at officers and hit two, but no one was injured. He was detained and arrested. Dallas has claimed that the former headquarters was built by his grandparents and that he has ownership rights to the property. Dallas was released on $5,000 bail and ordered to have no contact with the police officer complainants and to not go inside 100 yards of the ex-prison service property. Acting Puisne Judge Juan Wolffe ordered a mental health assessment and a social inquiry report on Dallas. He warned Dallas that he must follow his bail conditions. Mr Justice Wolffe said: “If you don’t, you could find yourself back in these courts and dressed in orange. “The fact that I gave you bail does not guarantee that I will not incarcerate you in relation to sentencing.“You have to be on your best behaviour. Stay away from that place.” Mr Justice Wolffe adjourned the case until February 3.
