The apprehended foreign nationals had reached Bihar via Nepal. A joint team of SSB and Bihar Police reached the Ghodasahan bus stand and launched a search, an official said. Four of the foreigners arrested are Sudanese, and one is a Bolivian national. Recently, the SSB apprehended five prisoners who had escaped from a jail in Nepal and were attempting to cross into India. India and Nepal share an open, 1,751-km-long border across five Indian states -- Uttarakhand, Uttar Pradesh, Bihar, West Bengal, and Sikkim.
