Christchurch police are trying to locate a man in relation to a firebombing at a residential address in Hornby.
Tony O'Riley, who may also be using the name Frank Barnett, is believed to be in the Ashburton area but police believe he may be linked to the Tuesday night attack.
Detective Damon Wells says the man's not believed to be a risk to the public but people shouldn't approach him.
Any sightings should be reported to the police.
