"Two skinheads beat me several times on my head with wooden sticks," the lawyer, Viktor Parshutkin, told RIA Novosti. The attack occurred late on Thursday.
Parshutkin claimed that one of the attackers said he had a "mission to kill the lawyer" suggesting the incident was linked with Russia's Constitutional Court ruling in favor of his client.
Meanwhile, Aslamazyan has not confirmed the information saying that she "could not get in touch with her lawyer."
Aslamazyan, a Russian national, who headed the Educated Media Foundation, was detained in 2007 by Russian custom officers for failing to declare foreign currency of around $2,800 more than the permitted sum of $10,000.
The court ruled on Tuesday that by charging Aslamazyan with smuggling the entire sum, including the permitted amount of $10,000, the seriousness of the accusations had been inflated, which was unconstitutional and violated the principles of equality and justice.
Aslamazyan should have been charged with an administrative offense which carries a fine of 1,000 to 2,500 rubles ($43-$106), the court said. The lawyer of Aslamazyan said that the court decision meant that "hundreds of thousands" of similar smuggling cases would also be subject to review.
Formerly known as Internews Russia, the Educated Media Foundation was involved in training broadcast journalists, who were largely from the Russian provinces.
Last April, police conducted a raid on the NGO's Moscow headquarters, seizing computers and financial documents, the group was ordered to suspend its operations following the raids, and was then forced to close down altogether. Aslamazyan was placed on the federal wanted list after leaving Russia.
The case against Aslamazyan prompted more than 2,000 Russian journalists to send an open letter of protest to former-president Vladimir Putin. The journalists claim the proceedings against Aslamazyan were launched to deter foreign-funded NGOs from meddling in Russian politics.
