Ahmed Raza Hasan Mehdi, the primary suspect in the murder of a Bangladeshi Hindu police officer, was arrested at Delhi's Indira Gandhi International Airport while attempting to flee to Europe. Authorities intercepted him during the immigration process as he was trying to leave. Following the necessary legal procedures, he was subsequently deported back to Bangladesh.

The incident is linked to the violent protests that erupted on August 5, 2024, amid widespread demonstrations against then-Prime Minister Sheikh Hasina in Bangladesh. During these protests, a mob attacked the Baniachang police station, resulting in the murder of Sub-Inspector Santosh Chowdhury, who has also been referred to as Santosh Sharma in some reports. Ahmed Raza Hasan Mehdi had openly claimed responsibility for this murder in a viral video from 2024, which led to heightened alertness from security agencies.

The targeted killing of police officer Santosh Chowdhury highlights the severe breakdown of law and order during the protests, reflecting ongoing tensions in Bangladesh. This incident not only underscores the risks faced by minority groups in the country but also raises concerns about the safety of law enforcement personnel amid political unrest, necessitating a reconsideration of security protocols and community protection measures.
