Officials in the eastern Ukrainian city of Kharkiv said on April 22 that former Prime Minister Yulia Tymoshenko has been returned to prison after refusing medical treatment at a local clinic.
Tymoshenko had been taken to the clinic on April 20 with severe back pain but was returned to prison after officials said she "categorically" refused treatment.
Western doctors who earlier examined Tymoshenko said the former premier had expressed fear she would be poisoned or deliberately infected with a disease if placed in a Ukrainian medical facility.
Her supporters say she was moved to the clinic under coercion.
Tymoshenko is serving a seven-year prison sentence after being convicted of abuse of power in a case she says is politically motivated and an attempt by her rival, President Viktor Yanukovych, to silence her.
