The Centre has sought a report from the Uttar Pradesh government on violence in Muzaffarnagar and directed it to take strong action to curb riots.
Home Ministry officials are in regular touch with the Uttar Pradesh government and have assured it of all possible help to control the violence in the western UP district.
Officials sources said the Centre has asked the state government to take necessary steps to ensure that communal tension does not spread to other parts of the state.
If necessary, steps like preventive arrest and house arrest of those who may create trouble to disturb peace should be taken, the sources said.
The Home Ministry is particularly worried that there have been attempts to break the social fabric of UP in the recent past and such attempts have increased recently, they said.
Home Minister Sushilkumar Shinde has already spoken to Uttar Pradesh Chief Minister Akhilesh Yadav and discussed the issue on Saturday.
The Centre on Friday had held a meeting with Chief Secretaries and DGPs of seven states and reviewed the situation arising out of communal violence in different parts of the country.
Army personnel today staged a flag march in riot-hit areas of Muzaffarnagar district where the toll in clashes between members of two communities rose to 12 even as 30 persons have been arrested for the violence.
Tension has been running high since three persons were killed in Kawal village on August 27 .
