Sri Lankan police have apologised after wrongly identifying a female American Muslim activist as a suspect in the deadly Easter bombings.

On Thursday, police issued a flyer with the names and photos of six people – three men and three women – wanted in connection with attacks that killed more than 250 people.

Among those listed was a woman identified as Abdul Cader Fathima Khadhiya, accompanied by a photo of a woman in a headscarf purported to be the individual wanted for questioning.

But the photo in fact showed Amara Majeed, an American Muslim whose parents are Sri Lankan immigrants and who wrote an open letter to President Donald Trump in 2015 about his rhetoric on Muslims.

“Hello everyone! I have this morning been falsely identified by the Sri Lankan government as one of the isis Easter attackers in Sri Lanka,” Majeed wrote on her Facebook page.

“What a thing to wake up to! This is obviously completely false and frankly, considering that Muslim communities are already greatly afflicted with issues of surveillance, I don’t need more false accusations and scrutiny.”

Sri Lankan police later replied with an apology for the “inconvenience” caused.

Police later issued a statement confirming that the photo published was not of the suspect. “The individual pictured is not wanted for questioning,” the statement signed by the police spokesman Ruwan Gunasekera said.

It added that an individual called Abdul Cader Fathima Khadhiya was, however, still wanted for questioning. On Friday, @SriLankaPolice2, the account that posted the tweet, was deleted.

The blunder came after Sri Lankan authorities revised the death toll in the attacks, from nearly 360 to 253. Authorities said some victims had been double-counted because bodies were blown apart in the attacks and misidentified.
