The blast at Rameshwaram Cafe in eastern Bengaluru occurred just after 1: 00 p.m. (07:30 GMT) on Friday when crowds from nearby offices were lined up for a quick meal. State Home (interior) Minister G. Parameshwara said all the injured were in hospital and none of them were in danger.

At least eight people were injured in India’s technology hub of Bengaluru on Friday when a suspected home-made bomb went off during lunch hour at a popular café, authorities said.

The blast at Rameshwaram Cafe in eastern Bengaluru occurred just after 1: 00 p.m. (07:30 GMT) when crowds from nearby offices were lined up for a quick meal.

A “small improvised explosive device” exploded at the busy eatery, causing panic, Siddaramaiah, the chief minister of Karnataka state of which Bengaluru is the capital, wrote on the social media platform X (formerly Twitter).

Siddaramaiah, who goes by one name, said preliminary investigations suggested the explosive was hidden in a bag left by someone who had breakfast at the cafe.

“Around eight people were injured in the incident,” he said, promising “strict action against the culprits”.

The minister said police were investigating the incident. “Whoever did this will be found out,” he added.

State Home (interior) Minister G. Parameshwara told reporters that all the injured were in hospital and none among them were in life-threatening condition.

Divya Raghavendra Rao, co-founder and managing director of the cafe chain, said she was told there were two explosions within 10 seconds of each other.

“It happened in the area where customers wash their hands. … Something that was kept in a bag exploded,” Rao told the local TV9 news channel.

Mobile camera videos shot soon after the blast and aired by local TV channels showed a cloud of smoke in the restaurant and one employee walking away with his hands covering his ears.

Some injured men were being helped to walk away by employees, their hands wrapped in bandages. A pillar inside the cafe was damaged.

The CCTV footage of the café has been handed over to police, and investigations about the cause of the blast were under way.

Bengaluru, known as “India’s Silicon Valley”, is home to many of the country’s top information technology companies.
