Of the 25 polling stations, 13 are in Patliputra and 12 are in Munger constituency, official sources said.
The Election Commission (EC) will inform about the repoll date later. There will be no repoll where people voluntarily boycotted voting, they added.
"Among the polling stations where repoll will be held, four are the ones located in Jamalpur where we could not send our polling personnel due to security reasons.
"Scuffle was reported at four polling stations, while EVM was broken at one. The rest are such where replacement of faulty EVMs took much time and hampered voting," Additional Chief Electoral Officer R Lakshmanan told reporters.
