A 50-year-old man has been detained for questioning by the Delhi police in connection with the car bomb attack on an Israeli embassy vehicle in Delhi in February.

The suspect was picked up from the capital and is being questioned, police sources said.

Israeli diplomat Tal Yehoshua and the driver of the vehicle were among the four people injured in the blast after a magnetic bomb stuck to the vehicle went off.

When asked whether any person has been detained in connection with the February 13 attack, Delhi Police Commissioner B K Gupta said, "We will let you know".
