London - A reward of up to one million pounds (1.65 million dollars) for information leading to the arrest and prosecution of the people behind Britain's biggest jewelry heist has been offered, investigators reported Friday.

The reward is being offered by the firm Tyler and Company on behalf of interested insurers.

Police spokeswoman Pam Mace added: "I'm directing my appeal at people, and that includes criminal associates, who know who these robbers are and where they are."

Two "smartly dressed" armed robbers raided a central London jewel shop on August 6 and got away with precious items worth 40 million pounds, Scotland Yard said Tuesday.

"We continue to actively pursue a number of lines of inquiry," a police spokeswoman said Friday.(dpa)
