arson

n. deliberate and malicious burning of property

Arson, called fireraising in Scots law, is the crime of setting a fire for an unlawful or improper purpose. The criminal damage of property in English law has been consolidated into a single offence in the Criminal Damage Act 1971 although the use of the word has been retained. The motives of arsonists vary. The possibility of financial gain often drives arsonists to file fraudulent insurance claim after setting fire.
