Due to some confusion, six Chinese nationals, including two women, entered India on Wednesday. They had come to see Bageshwari temple in Nepalgunj, Senior Superintendent of Police (SSP) Gaurav Grover said.
"Prima facie, the probe does not show anything suspicious about them due to which they were neither arrested nor detained. Due to language problem, the probe is taking time," he said.
All of them have a visa from Nepal, he added.
"Due to security reasons, we cannot reveal their names till the probe is over," the SSP said.
