(CNN) -- North Korea has released a South Korean fishing boat and its crew, whom it seized last month, the South's Coast Guard said Tuesday.
The seven crew members will arrive in South Korea late Tuesday, Officer Heejin Kim told CNN.
The North's navy intercepted the boat in its waters in August, state-run media said Monday.
The illegal fishing operation in the Sea of Japan on August 8 was "an intolerable infringement upon the sovereignty" of North Korea, the KCNA news agency said.
But North Korea had said it would return the boat and crew on humanitarian grounds, KCNA reported.
North Korea says the Sea of Japan is actually the East Sea of Korea.
In August, a U.S. congressman submitted a resolution urging North Korea to release the crew -- four South Koreans and three Chinese, according to South Korean state-run media.
