Estranged wife of Ajay Katara, the prime witness in Nitish Katara murder case, was on Tuesday arrested in connection with a forgery case.
Tannu Choudhary was arrested by Sahibabad police in Ghaziabad for the one-year-old case, SSP Deepak Ranjan said.
Earlier, a court had issued non-bailable warrant against Choudhary who was at large.
Ajay had lodged an FIR last year, alleging that Choudhary and former Rajya Sabha MP D P Yadav had committed a forgery of Rs six lakh with him.
Yadav is the father of Vikash Yadav who is the prime accused in the Nitish Katara murder case.
