Armed Sunni Muslim separatist groups in eastern Iran have stepped up attacks against security targets in recent months.
"These 14 people were kidnapped around 4 or 5am in Lulakdan border area," IRNA quoted the unnamed official as saying.
Lulakdan is in Sistan-Baluchestan, a mainly Sunni province that has long been plagued by unrest from both separatist militants and drug smuggling gangs.
In September, the Revolutionary Guards killed four Sunni Muslim militants at a border crossing with Pakistan, including the second-in-command of Jaish al-Adl, a group that has carried out several attacks on Iranian military targets in recent years.
The official said some of the security forces were members of Basij volunteer paramilitary force, a part of the Revolutionary Guards.
Iran says militant groups have safe havens in Pakistan and has warned it will hit their bases there if Islamabad does not confront them.
