The killing of a Hindu man during recent violent protests in Bangladesh has pushed already strained ties between Dhaka and Delhi into a deeper crisis.
As the two neighbours accuse each other of destabilising relations, questions are growing over whether their once close, time-tested relationship is fraying beyond repair.
In India, the episode has sparked protests by Hindu nationalist groups. The man who was killed - Dipu Chandra Das, 27 - a member of Bangladesh's Hindu minority, was accused of blasphemy and beaten to death by a mob last week in Mymensingh, in northern Bangladesh.
The incident happened as violent protests broke out over the murder of Sharif Osman Hadi, a prominent student leader, in the capital, Dhaka.
Hadi's supporters alleged that the main suspect, who they say is linked to the Awami League - the party of deposed prime minister Sheikh Hasina - had fled to India, further fuelling anti-India sentiment in Muslim-majority Bangladesh. Bangladeshi police, however, said there was no confirmation that the suspect had left the country.
