"The US has provided credible evidence (on Lakhvi) to Pakistan," a senior US official told PTI on condition of anonymity.
The official, however, did not give any details on the issue, saying this is an ongoing legal matter.
The information provided by the US to Pakistan on Lashkar-e-Taiba (LeT) operations commander Lakhvi and others related to the Mumbai terrorist attack is credible, the official said.
Various security agencies and intelligence wings of the United States have done their own investigation with regard to the Mumbai terrorist attack.

The information comes after the US last week said there is a strong counter-terrorism cooperation with Pakistan and urged Islamabad to follow through on its commitment on bringing to justice the 26/11 perpetrators.
"The Government of Pakistan has pledged its cooperation in bringing the perpetrators, financiers and sponsors of the Mumbai terrorist attacks to justice, and we urge Pakistan to follow through on that commitment," State Department Spokesperson Jen Psaki had said.
Lakhvi and six others -- Abdul Wajid, Mazhar Iqbal, Hamad Amin Sadiq, Shahid Jameel Riaz, Jamil Ahmed and Younis Anjum -- have been charged with planning and executingthe Mumbai attacks in November, 2008, that left 166 people, including six Americans, dead. The trial has been underway in Pakistan since 2009.
