Telugu Desam Party president N Chandrababu Naidu was on Thursday taken into preventive custody at the Visakhapatnam airport citing 'safety' concerns. Tension prevailed near the airport with TDP workers repulsing YSRC activists who tried to block Naidu's convoy. According to Visakhapatnam City Police, Naidu was taken into preventive custody for "his safety and security". The Leader of the Opposition in the state assembly was sent back into the VIP lounge inside the airport. The TDP chief arrived in Visakhapatnam on Thursday afternoon as part of his state-wide Praja Chaitanya Yatra but the YSRC organised a protest opposing his visit.
