British detectives holding three people over the $87 million security depot heist in Kent said Friday that a car used by the armed robbers had been recovered.

The Volvo car is thought to have been used to abduct Colin Dixon, manager of the Securitas depot targeted during the raid.

It was found on fire in the village of Leeds, near Maidstone.

Police also said Dixon's silver Nissan Almera was found near a pub in Detling.

The news came after a 41-year-old woman was snared at a Building Society in Bromley on suspicion of handling stolen goods.

Sky News Crime Correspondent Martin Brunt said she is suspected of trying to deposit $10,000 which is being linked to the raid, the biggest in UK history.

A man aged 29 and a 31-year-old woman are also in custody, having been arrested in the Forest Hill area of south London on Thursday evening.

They will be interviewed on suspicion of conspiracy to commit robbery.

A 100-strong police team is hunting the gang of at least six armed robbers who raided the Securitas depot in Tonbridge, Kent.

A reward of up to $3.5 million has been offered to help police catch the "gangsters" responsible for the robbery.

Police say it was carried out with "military precision" by professional robbers operating at the "top level" of organized crime.

Detectives believe there is a strong possibility the gang had "inside" help.

They held Dixon at gunpoint and took his wife Lynn, 45, and eight-year-old son Craig hostage, threatening to kill them if he refused to cooperate.

A Securitas spokesman said at least $43 million was known to have been taken but the final figure could be twice that.
