Some 6,500 supporters of Yoon were gathered at the residence on Wednesday, and some ruling party lawmakers were forming a human chain to block the execution of the arrest warrant, Yonhap news agency said.
The team executing the arrest warrant, made up of the Corruption Investigation Office for High-ranking Officials (CIO) and the police, secured a re-issued warrant on Jan 7 and has held multiple meetings in a bid to ensure a successful execution.
