The police had earlier in the day arrested three accused, all minors, in connection with the case.
A Swiss couple, hailing from Lausanne in Switzerland, was allegedly brutally thrashed by a group of youths in Agra's Fatehpur Sikri on Sunday. The duo was reportedly seriously injured in the attack and is currently admitted in a hospital in Delhi.
External Affairs Minister Sushma Swaraj also sought a report from the Uttar Pradesh Government over the incident.
The Swiss pair has alleged that they were followed by a group of people while ambling near the railway station. Later, the group started passing comments at them and forced the couple to stop and take selfies. The group's harassment soon turned violent and they suffered critical injuries. (ANI)
