"We've said we want to get past some of the tensions that have been there over the past several months and move on," State Department Deputy Spokesperson Marie Harf said.
She was responding to questions about the arrest of New York Police Department officer Manny Encarnacion, 49, at New Delhi airport on March 11 for possessing three bullets.
"We can't get into the specific case because of privacy considerations," she told reporters yesterday.
"I think we feel like we've moved past this and hope the Indians have as well," Harf said, adding that is a very close and a trusted partner.
"I can't share any more about this individual because of the privacy concerns," she added.
New York Congressman Peter King has termed the arrest of Encarnacion as "politically motivated" in response to the arrest of Indian diplomat Devyani Khobragade and has asked the State Department to seek the release of the officer.
Encarnacion has been charged with violating the Indian Arms Act of 1959 and faces up to seven years in prison.
He is forbidden from leaving India till his case has been settled in court. His next court appearance is on April 17.
"I write to express my grave concern over the arrest and pending prosecution of New York Police Department officer Manny Encarnacion in India," King said in a letter dated April 4 to Secretary of State John Kerry.
He said Encarnacion is being prosecuted for "unwittingly" having spare bullets in his luggage. King said bullets being found with Encarnacion was an "innocent mistake".
"This excessive act by the Indian government is clearly politically motivated in response to the arrest of India's then Deputy Consul General in December 2013 in New York for alleged visa fraud," King wrote in the letter.
"From all accounts this was the result of an innocent mistake. It is critical that the State Department intervene in this situation and request that the Indian government release him and permit him to return to the US," the Republican Representative from Long Island said.
New York Mayor Bill de Blasio also said he is "troubled" by Encarnacion's detention and hoped that the police personnel would be treated fairly by Indian officials. "Obviously we want to know a lot more about what's going on," he said.
"But so far, from what I'm hearing, I'm troubled by it and I want to make sure were providing support to him and make sure he's not being treated unfairly."
Police Commissioner Bill Bratton said the department is "staying very engaged with that issue in India. We are certainly concerned for that officer and for his wife whos there with him in India at this time.
"But that's a process that's moving slowly in the India justice system but we're staying informed."
New York Police Department Sergeant Carlos Nieves said he is allowed to carry the ammunition in the US but "obviously" not in India.
"He's not allowed to leave (India). He has a trial date coming up," he said.
According to a report in the New York Post, as Encarnacion was being arrested, an airport officer allegedly mentioned the arrest and strip-search of Khobragade last year.
"You guys like to strip-search our diplomats,' the officer allegedly told Encarnacion.
Encarnacion had initially left the bullets in his jacket pocket after he had been to a NYPD firing range for recertification and forgot to remove them, the Post quoted sources as saying.
