AVA- The blast occurred in front of a joint security checkpoint at around midday in Police District 10 in Helmand's provincial capital Lashkar Gah city, the report said, adding the blast also caused destruction.
No group has claimed responsibility for the attack so far.
Helmand, notorious for poppy growing, is also a known Taliban stronghold.
The Afghan security forces' casualties have risen since the beginning of 2015 when Afghan soldiers and police assumed full responsibilities of security from the U.S. and NATO troops.
Nearly 100 Afghan security force members lost their lives during clashes and blasts elsewhere in the country within the past several days.
