Police have urged Tokyo Electric Power Co., Nippon Steel Corp., NKK Corp. and Toppan Printing Co. to cut off long-standing transactions with firms linked to a major underworld syndicate that officials suspect effectively amounted to payoffs, sources said Tuesday.

They claim the money was paid to the two firms for the leasing of plants for offices and purchasing of tea products.
