Three members of a Dum Dum family were arrested on Thursday for allegedly setting their 14-year-old domestic help, Tapati Das, on fire.
The incident happened in a third-floor flat of a four-storey building at Bediapara in south Dum Dum on Wednesday night.
A resident of the building told police that he saw the girl rush out of the flat covered in flames. She was screaming and fell down on the staircase landing. The resident, along with others, wrapped her with blankets to extinguish the flames.
Tapati was taken to RG Kar hospital where she died early on Thursday.
The girlís uncle lodged a police complaint against Tapatiís employer Seema Gupta and her family.
The police arrested Gupta, her daughter Sagarika and son-in-law Shibaji.
They were produced in a Barrackpore court, which remanded them in police custody for four days.
