Police seek Sydney trampoline arsonist INVESTIGATORS hope video footage will lead to the arrest of a person who set fire to a children's trampoline centre in western Sydney. The centre in Richmond has only recently reopened after the arsonist broke in during the early hours of July 5, doused the building with accelerant and set it on fire. The blaze caused about $400,000 of damage and put the business out of action for weeks. On Wednesday, police released CCTV footage of a person they hope will be able to assist their inquiries. Anyone with information is asked to contact police.
