Aarti hanged herself in her room yesterday, police said.
A suicide note has been recovered in which she has blamed her sister-in-law Shweta and her relatives for her suicide, police said.
The note alleged that Shweta didn't want to do household work and used to threaten Aarti and other family members that she would implicate them in a dowry harassment case if they asked her to do that, police said.
No arrest has been made so far and family members are being questioned, police said.
