Two officers have been arrested as part of an investigation into the alleged theft of several hundred pounds-worth of stock from a police station tuck shop.
The officers, based at Hailsham police station, East Sussex, have been released on bail and suspended from duty while an inquiry is conducted into the allegations.
A Sussex Police spokesman said today that the force's professional standards department, based at headquarters in Lewes, were brought in to investigate amid concerns over "significant stock loss" from Hailsham police station's tuck shop, which sells sweets, crisps and soft drinks.
It is understood that 16 people have been questioned, including 12 officers and four police staff.
The police spokesman said: "As a result of the initial investigation, a number of staff and officers have currently been withdrawn from operational duties pending further inquiries.
"The investigation is in the early stages and the affected staff will be interviewed in due course to determine whether they are involved or not. Two officers have been arrested, bailed and suspended from duty whilst the investigation is conducted."
The East Sussex division of Sussex Police has brought in replacement staff to ensure normal policing service during the investigation, the spokesman added.
Chief Inspector Tony Blaker, Wealden district commander, said: "The integrity of our staff is very important to us and when we identify problems such as this, we act swiftly and positively to resolve the issues.
"At this time there is no indication that any members of the public are affected or will be by the investigation."
