The youth, identified as Mapaga (22) and Yohan (22) from Gabon, and Guira (20) from Burkina Faso, suffered injuries on the head and legs when an angry crowd thrashed them after the trio allegedly molested a woman commuter who raised an alarm.
The police, however, said they have not received any complaint of molestation from any woman. "We have registered a case of rioting, causing hurt and damage to public property against unidentified persons.
Investigations are on," a senior Delhi Police official said. Video footages of the incident, which has since then gone viral on social networking websites, showed a large crowd cornering the three youth at a Delhi Police booth where they were beaten up with security personnel nowhere to be seen.
One of the three even climbed over the booth to save himself and was seen being pulled down by the crowd.
As the mob continued to throw objects at the three youth, loud cheers were heard in the background while some people were seen shooting the act on their mobile phones.
"We are trying to identify the attackers through the CCTV footage of the station. We have recorded the statements of the three youth," the official said.
