(JTA) — A dual citizen of Russia and Israel was beaten to death in St. Petersburg days before the birth of his first child.

Police arrested and later released on bail Ahmed Kharsha, 36, who is suspected of assaulting 27-year-old Mikhail Verevsky on March 28, the news site Fontaka reported Tuesday. He died in hospital from his injuries on Monday, according to the report.

The report did not contain details about the alleged motive. It said the victim was assaulted after 9 p.m. while he was returning home from a supermarket. Kharsha fled the scene after striking Verevsky on his limbs and abdomen, splitting his spleen and liver, the report said.

Verevsky’s pregnant wife was in the hospital at the time of the attack, Fontaka reported, where doctors said she would give birth imminently.

Kharsha is alleged to have committed manslaughter by “deliberate infliction of serious injury,” but police and prosecutors said the indictment against him may change following his alleged victim’s death.

Verevsky studied architecture and civil engineering in St. Petersburg before immigrating to Israel, where he served in the army for two years until 2012. He returned to Russia, where he volunteered at a shelter for abandoned pets.
