The Hyderabad High Court issued notices on Tuesday, to the Andhra Pradesh government, TDP MP Kesineni Nani, TDP MLA Uma Maheswara Rao and others, for allegedly abusing a senior bureaucrat.

The notice came after an incident where Nani and others entered into a verbal duel and obstructed the way of the State Transport Commissioner N Bala Subramanyam for about two hours, in Vijayawada last month.

The MP alleged that due to the "corrupt" practices of transport officials, around 400 private buses were operating across the state without permits.

He sought immediate seizure of private buses operating without permits.

"Around 150 buses which belong to Orange Travels are operating in Vijayawada and around 400 buses are operating across the state. Owner of Orange travels, Sunil Reddy, is a 'benami' (proxy) of YSR Congress chief YS Jaganmohan Reddy. He is influencing transport department officials by offering bribes," he had alleged.

Subramanyam denied the allegations and said every bus was paying taxes to the Transport Department and operating with permit.

A video also surfaced that showed the TDP MLA Umamaheshwara Rao roughing up one of the security personnel of the Commissioner.

The incident, which occurred on March 25, had snowballed into a major controversy with transport employees threatening to go on strike if the MP and MLA did not apologise.

Following this, Andhra Chief Minister Chandrababu Naidu reportedly stepped in, and asked the TDP leaders who were involved, to apologise.

A week after that, Nani shut down Kesineni Travels along with all 170 luxury buses of the 88-year-old company.

With this, one of South India's largest private travel agencies, came to a halt and its offices in Andhra Pradesh, Telangana, Karnataka and Tamil Nadu were closed down.

The HC has now asked the state government what action it has taken on the incident, and adjourned the case to June 13.
