Students and pro-Telangana activists stormed exam centers in Hyderabad Sunday, where the Andhra Pradesh Public Service Commission was being given.
The protesters barged into the examination hall of the Institute of Advanced Studies shouting slogans, and took away the answer sheets from students who were taking the exam.
Protestors burned the answer sheets, as police and protesters clashed.
The Osmania University Students Joint Action Committee had called for a shutdown to protest the exams. Their demand... until more public service jobs are available for people in the Telangana region.
As the mob got more violent, the police resorted to baton-charge and fired teargas shells.
Police arrested 60 protesters.
[Mahesh Chandra Laddha, Deputy Commissioner of Police]:
"The exam was peaceful, suddenly there was stone pelting from inside the campus building and the campus compound. So police had to disperse them. We used mild lathi charge (baton-charge) and all those things. And now the situation is definitely under control."
The incident took place even after tight security arrangements in all the examination centers.
Over 100,000 candidates are appearing for the examination for 198 posts in civil services.
Telagana activists want a separate state to be carved out of Andhra Pradesh.
