Congress MP Rakesh Rathore was arrested from his residence here in a rape case on Thursday, a day after the Allahabad high court rejected his anticipatory bail plea.
Rathore was addressing a press conference when Kotwali Nagar police reached his residence to take him into custody.
An FIR was lodged against Rathore on January 17 on a complaint by a woman who accused him of repeatedly raping her over four years after promising to marry her.
Authorities are continuing their probe into the matter.
