It started as a normal morning in the upper house of Russia's Parliament, as a rubber stamp body for the Kremlin packed with wealthy members. But within minutes, the country's top law-enforcement officials turned up to detain a senator on murder charges as he waited for debate to begin.

The unprecedented scene saw Russia's youngest senator, 32-year-old Rauf Arashukov, led from the floor of the Federation Council on Wednesday on charges of murder and organised crime. As officials laid out their case to his colleagues to lift his immunity as a parliamentarian, he got up to leave the hall but was ordered to stay by Speaker Valentina Matvienko, she later told reporters.

Later, investigators released footage of him being led in handcuffs by police. He was charged with murder, participating in a criminal group and pressuring a witness. His father, an influential businessman in their home region, was also taken into custody, suspected of setting up the criminal group and fraud in a case involving hundreds of millions of dollars in stolen natural gas.

Rauf Arashukov denies all the charges but has no further comment, according to his lawyer, Evgeny Ustin, the RIA Novosti news agency reported. His father's lawyer couldn't be reached for comment.
