Mr Webster moved to New Zealand after his first wife's death
A man at the centre of an investigation into his wife's death 14 years ago is being hunted by police in New Zealand.
They are investigating a crash involving his second wife in similar circumstances to the one which killed his first wife in Aberdeenshire.
Claire Webster died in 1994 after the car driven by her husband Malcolm hit a tree near Oldmeldrum.
His second wife survived a crash in Auckland in 1998 but was found with a strong sedative in her system.
An investigation into Claire Webster's death concluded that she had died accidentally.
However, Grampian Police is now re-examining the crash following a crash involving his second wife, Felicity Drumm.
Mr Webster moved to New Zealand where he lived with Ms Drumm.
After the crash involving her, the 48-year-old failed to appear in court on a number of charges and is the subject of four warrants, which include arson and disabling or stupefying his victim.
That led to questions over the exact circumstances surrounding his first wife's death.
A New Zealand Police spokesman said: "We can confirm that Malcolm John Webster is the subject of four warrants for his failure to appear in the North Shore District Court of New Zealand on July 13, 2000.
"He failed to appear at court and full warrants were issued. They are still live. Two of them are for arson, the third is for selling, giving, supplying or administering a drug and the fourth is for disabling or stupefying his victim, his then wife.
"The arson charges relate to a fire at the home of his then wife's parents."
Spotted in Scotland
Reports indicate Mr Webster is now back in the UK and has been spotted in Oban in Argyll and Bute, as well as Devon and Cornwall.
A Grampian Police spokesman said: "Grampian Police can confirm it is reviewing the circumstances surrounding a road traffic collision on May 28, 1994, on the Old Meldrum to Auchenhuive road in Aberdeenshire, where a woman tragically died.
"This remains at a very early stage and as is usual in such circumstances the Crown Office and procurator fiscal service are fully aware of the matter."
