looked like a sleeveless NATO jumper and were supplied by Highmark. New stab vests were issued from 2000 that featured blue and white chequered reflective bands across the front and back, force insignia sewn on the left breast, and a blue and white reflective (or occasionally black and white embroidered) 'POLICE' patch sewn onto the back. There were several attachments for handcuffs and other equipment. A black fleece with the Strathclyde Police logo was worn over body armour before November 2009, when they were replaced by microfleeces. There is also a fluorescent 'bomber style' jacket with similar reflective markings to the stab vests, which they were normally worn over. Also issued were black waterproof trousers and black (Constables and Sergeants) or brown (Inspectors and above) leather gloves. Personal equipment consisted of a Police duty belt holding handcuffs (Hiatts Speedcuffs or TCH-840 Rigid Handcuffs), a 21" Autolock baton with a Hindi cap (Mounted Unit officers were supplied with the longer 26" Autolock batons) and CS Spray. Also carried were a small first aid kit, torch, leg restraints, keys, utility pouch etc. Motorola MTH800 radio handsets, connected to the UK's Airwave TETRA radio network, were issued to officers when on duty. This style of uniform was later adopted by all police forces in Scotland, with slight insignia variations, and subsequently by Police Scotland. The Strathclyde Police Air Support Unit operated Scotland's only police helicopter; a Eurocopter EC 135T2+ (G-SPAO) based at the Glasgow City Heliport. This helicopter was painted in PSDB highly conspicuous colours of dark blue and yellow. The aircraft was supplied on a contract basis by Bond Air Services. Headquarters The Strathclyde Police Headquarters were located at Pitt Street in Blythswood Hill, Glasgow. The building was originally erected in 1934 as Glasgow and West of Scotland Commercial College, later the Scottish College of Commerce. In 1964 the Scottish College of Commerce combined with the Royal College of Science and Technology to form the University of Strathclyde. There were plans in place before dissolution to relocate the HQ to Dalmarnock on the outskirts of Glasgow. The Pitt Street headquarters of Strathclyde Police were demolished in early 2019.
