The protest outside the Concert Hall in the centre yesterday of the Swedish capital came three years to the day after the writer and human rights activist was awarded the Nobel Peace Prize.
"Four people were prevented from entering the restricted area around the Concert Hall," Stockholm's police said, confirming the TV report.
The men had been arrested on charges of disorderly conduct, according to a police spokeswoman, who did not give the nationality of the four.
He was prevented from attending the Nobel Peace Prize award ceremony in Oslo the following year.
Earlier this year, more than 140 Nobel laureates urged China to release the activist in a letter signed by 400,000 people from more than 130 countries.
