Bihar Chief Minister Nitish Kumar's convoy was pelted with stones on 12 January during his state-wide 'Vikas Samiksha Yatra', which he began in December 2017.
The people behind the incident or their motive were not immediately known.
An official release in Patna quoted Kumar as having told a public meeting in Dumraon block of Buxar district that the incident would be thoroughly probed to ascertain the cause for it.
Referring to the opposition RJD, Kumar said, "Those involved in politics of provoking and misleading the people have problems with our commitment to development. But we are not bothered about them."
Some people feel disturbed over my commitment to progress of the state. They try to mislead and provoke others, but people should not get perturbed over such minor happeningsNitish Kumar, CM, Bihar
An official accompanying the Chief Minister told PTI that some people hurled stones at the convoy but that did not hamper its movement.
He said the convoy kept moving towards its destination, where the Chief Minister launched 168 schemes involving an expenditure of Rs 272 crore before addressing a public meeting.
He said the purpose of his tour was to assess ground realities and progress of development schemes so that basic amenities like roads, clean water and power reached every village and locality in the state.
Kumar also spoke at length about prohibition imposed by his government and its drive against dowry and child marriage, besides measures for skill development to ensure youth got better job opportunities.
He told security personnel deployed at the venue of the public meeting not to worry about protests or if somebody wanted to raise slogans and show black flags.
