"Magomed Chakhkiyev was released without any demands. He feels well, although he had been held for two months. After medical examination and necessary treatment, he will resume his duties in the near future," the source said.
Police detained several people suspected of abducting the official.
On February 27, Chakhkiyev was traveling home to Nazran, the republic's capital, when his car came under automatic rifle fire. The driver lost control of the car and collided with a crash barrier. Having knocked out the driver, the culprits abducted the MP. It was unknown whether Chakhkiyev had sustained any injuries.
Chakhkiyev is chairman of the legislature's Committee on Agrarian Policy, and the Ingushetian president's father-in-law.
"The attack on and abduction of MP Chakhkiyev is a criminal attempt to destabilize the situation in the republic," the ministry spokesman said then.
