The Supreme Prosecutors’ Office summoned on Monday former Vice Knowledge Economy Minister Park Young-joon for questioning on May 2 as part of its investigation into a bribery scandal involving a construction project named Picity.

The prosecutors raided the house and office of a close associate of Park identified as Lee over the weekend in relation to the allegation.

Prosecutors reportedly discovered dubious money exchanges between Park and Lee, and are looking for any connection with 1 billion won($800 million) allegedly delivered from Picity to Park.
