A Chinese college student detained in northern Iraq was freed by local police on Monday, according to Chinese embassy in the country.

Liu Tuo, a student with China's Peking University and a archaeological major, has been freed and is in good health. He has arrived in the Iraqi capital of Baghdad.

The embassy also said that the released student is going to return home soon.

Earlier this month, Liu was detained as reports said he was suspected to have links to the Islamic State militant group, but was later proved to be false.

Reports say he had gone to Iraq to visit historical sites, and was mistakenly thought as a terrorist.
