The questioning was over funds he received from former prime minister Datuk Seri Najib Razak.
Former Johor Bahru MP Shahrir Samad left the Malaysian Anti-Corruption Commission (MACC) headquarters in Putrajaya at 5.30pm after being questioned for seven hours.
Speaking to reporters outside the MACC office, he said he was called to give his statement on the RM1 million cheque given by Najib in November 2013.
“I would be the last to know where the money originated from.
“As Johor Bahru Umno chief, I asked for funds from him to run activities at the division level,” he said, responding to questions on whether he knew the source of the money.
When asked if he would return the money, as what MACC chief commissioner Shukri Abdull had suggested, Shahrir said the money had been fully spent on political activities in Johor.
“Both my account and that of Johor Bahru Umno have been frozen.
“To me, the money was part of political funds and not illicit funds,” he said.
