The Helsingin Sanomat reported Monday while Nekrasov's documentary about the assassinated secret agent has been surrounded with controversy, an initial investigation into the incident ruled it a routine break-in.

"We have no reason to react," National Police Commissioner Markkku Salminen said of the crime.

Nekrasov reported the break-in last Friday, one day before his film "Rebellion: The Litvinenko Case" was to premiere at the Cannes Film Festival.

In his documentary, Nekrasov follows the life of the noted spy and Russian journalist Anna Politkovskaya's murder.

The newspaper said such incendiary subject matter and the fact that no property was stolen from Nekrasov's Finland home have led to allegations that there was a hidden agenda to the crime.
