Who was detained?
The failed assassination attempt carried out by 63-year-old Ukrainian Serhii P. took place in Irpin, Kyiv region.
The man planted an improvised explosive device under a car used by the intended victim.
The device was to be detonated remotely using a mobile phone. It failed to explode because the mechanism did not work.

The Ukrainian was charged with attempted murder using explosives, which he possessed without authorisation. A court ordered him to be held in pre-trial detention for three months.
