Ten days after the blast outside the Delhi high court, a bomb went off at 5.35pm in a private hospital, 6 km from the Taj Mahal, in the tourist city of Agra in Uttar Pradesh, injuring six people.
The explosion shattered windowpanes in the reception area of Jai hospital on the Agra-Kanpur highway, where 10 to 15 people were seated in steel chairs.
Preliminary reports said the crude bomb may have been kept below one of the chairs at the hospital .
"There was a bang followed by smoke and chaos," said Gayatri Devi, 35, who had come from neighbouring Hathras town for her husband's treatment.
"The samples collected have been sent to a forensic lab in the city," said PK Tiwari, inspector general of police, Agra range.
The anti-terrorism squad, already in the city for training, reached the spot in no time.
"It was a low-intensity explosion. No traces of any circuit or timer were found," said GK Goswami, senior superintendent of police for the ATS.
