The police had resumed guarding the teams after an incident in February in which a policeman was shot dead while protecting a polio vaccination team on the outskirts of Mardan.
District Police Officer Tahir Ayub told that unidentified armed attackers riding a motorbike attacked the security personnel on guard with the polio team in Par Hoti area of Mardan and one of them died on the spot while the other cop was injured.
“The polio team comprising two females and a male remained safe,” he added.
No has claimed responsibility for the attack but the authorities believe the outlawed militants groups had always been behind such attacks.
A superintendent of the health department in Mardan told media that the polio campaign in other parts of the district continued as per routine and the polio teams remained in the filed even after the attack.
The policeman Raj Wali from Katlang area of Mardan died on way to hospital while Ashfaq was injured critically in the attack.
