CPI-ML district secretary Niranjan Kumar said 15 party activists were taken into custody, but Bodh Gaya deputy superintendent of police Rakesh Kumar Dubey said only two protesters were detained.
Rajapaksa, heading a 50-member delegation, offered prayers at the Mahabodhi temple, Bihar’s lone world heritage site. His itinerary remained undisturbed by the protest.
He also visited the Sri Lankan Buddhist temple-cum-monastery and inaugurated golden railings around the Bodhi tree and laid the foundation stone of a cultural building.
“He also had refreshments with Buddhist monks of different countries,” said Bodh Gaya temple management committee secretary N Dorje.
Rajapaksa left for Tirupati around 2.35pm, Dorje added.
In Tamil Nadu, thousands of activists from the DMK, the Viduthalai Chiruthaigal Katchi and other Tamil groups wore black shirts and held protest demonstrations.
DMK chief M Karunanidhi, who led the protests in Chennai, said Rajapaksa was “systematically destroying Tamil culture, traditions and language in Sri Lanka”.
