A new house under construction in Tokyo's Tama City was torched on Saturday night, the sixth such house to be hit by an arsonist in the area since Sept 12.
All the fires took place within a 1.5-kilometer area, police said.
Despite night patrols by police in areas where new houses are being built in Tama, the arsonist struck again Saturday, TBS reported.
Flames were seen coming from the house at around 9 p.m. Fifteen fire engines were mobilized and after about 90 minutes, the fire was extinguished, but the 100-square-meter new house was completely destroyed.
According to investigators, some kind of oil has been used to start all six fires.© Japan Today
