An alleged arsonist charged over a fire in Albany’s industrial area on Saturday has been refused bail during a dramatic court appearance in which he repeatedly yelled at the magistrate and a police prosecutor. Shane Rex Mascull, 53, appeared in Albany Magistrates Court in police custody on Tuesday, charged with one count of criminal damage by fire. A Department of Fire and Emergency Services spokeswoman said the fire caused extensive damage and was attended to by four crews. The blaze took about an hour to extinguish fully, with the damage bill estimated at $20,000. Police prosecutor Sgt Mike Russell told the court about 8.30am on Saturday, Mr Mascull was at a transportable unit he leased in an industrial area on Chester Pass Road. Sgt Russell alleged he entered the unit, started a fire by “unknown means”, then left and locked the door. A witness saw smoke coming from the unit and used his mobile phone to film a man, alleged to be Mr Mascull, leaving. A man was also captured entering and exiting the unit on CCTV footage. Mr Mascull was arrested on Monday. Sgt Russell told the court Mr Mascull was homeless and itinerant and had more than 100 charges on his record for offences committed in other States. He said police had spoken to several witnesses, and obtained CCTV and phone recordings of the incident, and Mr Mascull owned the clothing the man seen in the footage was wearing Police had also confirmed with the alleged victim that Mr Mascull was leasing the property from them and he was the only person who had access to the unit. Sgt Russell opposed bail, saying Mr Mascull had an “abusive and aggressive” demeanour and he had done “nothing to indicate he will comply with bail”. He said Mr Mascull would “pose a threat” to the witnesses if granted bail. Magistrate Erin O’Donnell said the facts were “relatively strong” and the case would eventually be committed to the District Court. Mr Mascull was refused bail. During the hearing, Mr Mascull yelled at Sgt Russell and Ms O’Donnell several times that he had evidence of drug dealing, and refusing bail would result in a “removal of evidence”. After his bail was refused, he began yelling aggressively that he wanted the case taken to the District Court, causing Ms O’Donnell to order his removal from the courtroom. Mr Mascull is due to reappear in Albany Magistrates Court on December 22. The maximum penalty for criminal damage by fire is life imprisonment.
