(CNN) A prominent Bangladeshi-American blogger who spoke out for secular freedom has died after being attacked on a Dhaka street, a local police official said Friday.
Assailants attacked Avijit Roy, the founder of the website Mukto-Mona, and his wife Thursday night as they were walking back from a speaking engagement, said Krishna Pada Roy, a deputy commissioner with the Dhaka police.
Roy, an American citizen, died at a nearby hospital, the police official said. His wife suffered injuries of her own, including a severed finger.
The attackers carried knives and machetes.
A witness told CNN that an assailant pulled out "a big knife" and struck Roy from behind in the head and shoulders. Roy's wife also was hacked on the shoulders.
"I shouted for help from the people but nobody came to save him," she said. "No one came."
