The police official who opened fire on the teenager has been taken into custody.
The boy from Pakistan's Punjab province was shot dead by the police when he along with his friend Fahad, 14, were taking a selfie with a toy gun in Faisalabad on Monday.
The police personnel mistook Farhan for a robber and opened fire at the boys without any warning , said senior police officer, Faryad Cheema, who along with four other have been arrested.
It was later that the police officer discovered that the gun was a toy.
The boys suffered injuries and were taken to a nearby hospital. Farhan, whose condition was critical, died of excessive bleeding.
"A judicial inquiry team has also been formed to probe the incident," said Punjab Law minister Rana Sanaullah.
