MOSCOW?Police in the Russian capital have arrested a man who dismembered an acquaintance and kept him in his fridge, eating the liver, investigators said Tuesday.

Nikolai Shadrin has been arrested after police located the apartment where he killed a 40-year-old Muscovite, named as Ilya Yegorov, in early May.

"During the search of the apartment, tools used to dismember the victim and a human liver were found. Shadrin confessed to the crime and to having eaten part of his friend's liver," the Investigative Committee said in a statement.

Yegorov was killed on May 2, and police found human body parts, including feet, a hand, and part of a shoulder, in the Moscow river and various basements in western Moscow, said Aleksei Saveliev of Moscow's western district police.

At the time of his arrest, Shadrin was eating a stew of human liver, Saveliev said, according to RIA Novosti agency. The cannibal broke up the body with a small digging shovel and "was identified by his fingerprints."

Shadrin has been a patient in a psychiatric asylum, investigators said.
