The Justice Ministry's Immigration Bureau has introduced a section on its Web site that allows people to submit information on the identity, address or workplace of undocumented foreigners in a bid to track them down.

Since Monday, visitors to the bureau's home page have been able to access the form, which, once submitted, is sent directly to regional immigration bureaus covering the residence or place of employment of suspected illegal residents, according to a ministry spokesman.

Some regional bureaus have already received information gathered via the Web site regarding undocumented foreigners, he said.
