Pakistani intelligence agencies on Wednesday night claimed to have arrested an Indian national in connection with the Lahore [Images] car bomb blast earlier in the day.

"The accused was identified as Munir alias Satish Anand Shukla, a resident of Kolkata," TV channels quoted police sources as saying.

Some of the reports claimed that the arrested had earlier worked with the Indian High Commission in London [Images].

A woman was killed and four persons were injured when a car bomb went off in a high-security residential complex for government officials in the eastern Pakistani city of Lahore.

The explosion occurred at 9.20 am within the Government Officers Residences complex, an area in the capital of Punjab province, where senior government officials and judges reside.
