Belgian MEP Marie Arena was questioned in connection with the 'Qatargate' corruption scandal at the European Parliament.

Arena was not charged and was allowed to go home after a day of questioning, signaling a major step in the ongoing fourteen-month investigation.

Her lawyers assert her innocence, while Antonio Panzeri, a central figure in the scandal with repented status, has claimed Arena was not involved.

The case's integrity is under scrutiny after an audio recording surfaced featuring a principal investigator suggesting Panzeri may have been untruthful.

The investigation into the alleged corruption at the European Parliament continues.
