Police in Kasai City, near Kobe, Japan, arrested a 29-year-old factory worker named Yoshifumi Takabe on suspicion of burning down his own home on Sunday.

According to the police, the suspect said that his mother had gotten rid of his "valuable" Gundam plastic models, so he wanted to kill himself.

The suspect reportedly doused his room with kerosene and lit it with a lighter around 2:10 p.m. on Sunday. The resulting fire eventually burned down the two-story house, which was about 250 square meters (about 2,700 square feet) and made partially from wood.

The police investigators say that the suspect had doused himself with kerosene, but had escaped the fire without injuries. His 55-year-old mother was also in the house but escaped without injuries.
