The accused Shamshad had been lodged in jail in connection with the month-old case and recently came out on bail, SHO K P Singh said.
He had been pressurising the 25-year-old to withdraw her complaint but she refused to relent, he said.
The woman claimed in her complaint that Shamshad barged into her house yesterday and poured kerosene on her but she managed to escape before he could set her on fire, the SHO said.
