The arrested four were among the 16 persons who were identified in connection with the incident in front of a bar on the Guwahati-Shillong Road on Monday night, which led to a public outcry after a video of the assault by a TV channel was uploaded on Youtube.
After his force was slammed for delayed action, Assam DGP Jayanta Narayan Chowdhury said police is not like an "ATM machine" which can be present at the crime scene the moment one inserts a card in the machine.
Chidambaram said today no one should make light of an incident of molesting a woman or molesting a child and strongly condemned if any one tried to do so.
"If they have tried to make light of the incident I strongly condemn it. No one should make light of an incident of molesting a woman or molesting a child," he told reporters in Chandigarh. The minister said he would get in touch with Assam Chief Minister Tarun Gogoi over the incident.
The Home Minister was asked by a newsman to comment on Chowdhury's ATM machine remark and another remark by a senior police officer that the incident has been played up by the media in Delhi when molestation of girls from the North East in the national capital are brushed aside and suggesting that Delhi was a "rape capital".
"The remark is in poor taste. There is no such thing as rape capital. Every incident of molestation is condemnable," he added.
National Commission for Women (NCW) chairperson Mamta Sharma also slammed the state police for the 'ATM machine remark
