Members of India's National Investigation Agency (NIA) is on its way to Sri Lanka, CNN News 18 reported today.
The visit follows the Easter Sunday suicide bombings by Islamist extremists supportive of Islamic State, which left over 250 people dead.
Soon after the bombings it emerged that India had warned the Sri Lankan government about the attacks.
"We have our own FIR against ISIS modules. The visit is not to assist Sri Lanka with their probe but to see if an exchange of information and evidence gathered by us and them can be mutually beneficial,” a senior NIA official was quoted by the news site as saying.
Since the bombings, Indian authorities have made a number of arrests in Tamil Nadu and Kerala, in relation to the Sri Lankan attackers.
Meanwhile today India relaxed its travel advisory, urging citizens to nonetheless be "careful and vigilant".
"Security situation in Sri Lanka is gradually returning to normal with the lifting of curfew and restrictions on social media and the opening of schools. Indian nationals traveling to Sri Lanka are advised to be careful and vigilant," a statement read.
