Police are investigating reports of juveniles throwing rocks on the outskirts of Geraldton, as well as a possible serial arsonist. “We’ve had reports of damage on the Geraldton-Mount Magnet Road, we had some reports of kids there throwing rocks,” Geraldton police officer-in-charge Sen. Sgt Chris Martin said. “We’ll be working in conjunction with youth policing this week to identify those juveniles involved and speak to them over the dangers of throwing rocks etc. “We would just like members of the public to continue to report this behaviour to us immediately because obviously it’s incredibly dangerous.” Police are also investigating a skip bin fire at the Northgate Shopping Centre on the weekend, which they believe could be connected to a series of other fires. “We have some CCTV we will be going through over the course of the next few days,” Sen. Sgt Martin said. Police are linking the blaze to some bushfires lit within the past two weeks, and reiterate the dangers of lighting any kind of fire. “There was also a couple of reports two weeks ago of scrub-fires in the Woorree area, and this looks like it could be the same offender,” Sen. Sgt Martin said. “Skip fires, small rubbish fires and any kind of lighting of fire is dangerous and police want to remind the community of how easily a fire could get out of hand. “We’re looking for assistance from the public as to who might have seen the incident at Northgate.” Rewards up to $25,000 are on offer for information leading to the conviction of a person for arson in WA. Police are also calling for the community to be vigilant about their safety, to lock up their valuables and to report suspicious activity. Last weekend, Geraldton police attended 189 requests for assistance ranging from theft, burglaries, damages, suspiciously lit fires and rock-throwing. Police said in one burglary, on Acacia Street in Mount Tarcoola, a garage door was left open and a motorbike was stolen. Later in the day, the motorcycle was recovered on Broome Street, but police are attempting to uncover where the bike was between the theft and recovery and who was responsible. “Anyone who was living in the Spalding area, if they saw anyone pushing a bike on the road we’d love to hear from them,” Sen. Sgt Martin said. He said a couple of vehicles were broken into in Rangeway, where again the vehicles had been left unlocked with valuables in them.
