Mr Farinas staged a 134-day hunger strike last year High-profile Cuban dissident Guillermo Farinas has been detained and held in the city of Santa Clara.
It is the second time the psychologist, detained with at least 10 others, has been arrested in as many days.
Mr Farinas was taken into custody on Thursday afternoon, kept overnight and remains in custody, campaigners and relatives have said.
He gained international attention last year when he came close to death after staging a 134-day hunger strike.
His mother said he had been detained near the home of another local opposition figure named Idania Yanez Contreras.
“He was in the street when a patrol picked him up and I was told later that he had been detained,” Alicia Hernandez told the Associated Press news agency.
She said that she expected him to be released soon.
On Wednesday, Mr Farinas was arrested with at least 17 other people as they tried to prevent the eviction of a woman and her two children from a disused property in Santa Clara.
Earlier in 2010, he came close to death during his hunger strike in protest at the death of fellow dissident Orlando Zapata.
He ended the protest in July, when Cuban President Raul Castro authorised the release of 52 of the island’s most prominent prisoners of conscience.
Mr Farinas has spent eleven-and-a-half years in prison for a variety of offences and has staged more than 20 hunger strikes.
