A former Chubb employee has been charged with defrauding the insurer out of hundreds of thousands of pounds, Insurance Times has learned.
Kalpana Chandran, a claims examiner in the accident and health team, has been charged with 12 counts of fraud.
It is thought she denies the charges.
It is understood the charges relate to the creation of false claims files and the making of fraudulent payments.
The two largest alleged frauds are thought to be worth nearly £200,000 in total value.
Chandran's husband, Francis Peter, is also believed to have been arrested but was later released without charge.
A spokesman for Chubb said: "We can confirm that a member of staff at Chubb London has been charged with 12 offences under the Fraud and Theft Acts in connection with their duties at Chubb.
"The person appeared in Court on 1 February and has been remanded in custody for a further month."
Chubb would not comment further, but sources close to the investigation said over 40 claims files spanning a period of 18 months had been examined.
Chandran was unavailable for comment as Insurance Times went to press.
