Employees were told to leave the building during the search, RIA-Novosti said.
Alexander Papin, Yevroset's vice president for finance, told the agency that he did not believe the investigation was related to tax claims.
A spokesman for Yevroset could not be reached for immediate comment.
Police officials could also not be reached for comment.
Police raided Evroset last year in an investigation reportedly connected to the sale of contraband phones.
Evroset is co-owned by Yevgeny Chichvarkin -- a brash entrepreneur famed for his controversial public-relations stunts -- and director Timur Artemyev.
A Message from The Moscow Times:
Dear readers,
We are facing unprecedented challenges. Russia's Prosecutor General's Office has designated The Moscow Times as an "undesirable" organization, criminalizing our work and putting our staff at risk of prosecution. This follows our earlier unjust labeling as a "foreign agent."
These actions are direct attempts to silence independent journalism in Russia. The authorities claim our work "discredits the decisions of the Russian leadership." We see things differently: we strive to provide accurate, unbiased reporting on Russia.
We, the journalists of The Moscow Times, refuse to be silenced. But to continue our work, we need your help.
Your support, no matter how small, makes a world of difference. If you can, please support us monthly starting from just $2. It's quick to set up, and every contribution makes a significant impact.
By supporting The Moscow Times, you're defending open, independent journalism in the face of repression. Thank you for standing with us.
Remind me later.
