Moldova police detained earlier Friday Igor Velchev, suspected of killing Russian television NTV special correspondent Ilya Zimin on February 26.
Interior Ministry Georgy Papuk said Velchev, born in 1984 in Moldova, was also accused of forging documents in Moldova.
"After Russia's law enforcers present the Moldovan Prosecutor General's Office with the necessary documentation, we will extradite Velchev to Russia," Papuk said.
A spokesman for the Moldovan police said earlier the detention of Velchev was a success for the country's law enforcers, but refused to give the details of the arrest.
Zimin was found dead by colleagues in his Moscow apartment on February 27. An autopsy revealed he had died of head injuries and police said the door to the apartment had not been forced open.
Investigators on the case said Velchev met Zimin in Moscow February 25 and spent time with him at a Moscow night club until about two in the morning. They left the club together and went to Zimin's apartment, where an argument is said to have broken out before Velchev allegedly beat the reporter to death.
Early in March NTV said it would pay 1 million rubles (about $36,000) for information leading to the arrest of the suspect in the killing.
