A man has been arrested in connection with a knifepoint robbery in Abbeymead at the end of February.
The 18-year-old was arrested on suspicion of robbery and bailed to return to Gloucester police station on May 7, pending further inquiries.
The incident happened close to Laurel Gate at around 11.05pm on Monday February 24 after the two robbers, who were on bikes, followed four teenage males from Tesco Express in Abbeymead Avenue.
The offenders stopped the victims before one pulled out a knife and the other pulled out what is described as a black handgun.
Items including mobile phones and wallets were taken by the robbers before they made off. The victims, two aged 18 and two aged 17, were unhurt but badly shaken by the encounter.
A BMX and a black and white mountain bike are believed to be the bikes used by the robbers.
The first offender is described as white, in his early 20s, 5ft 9ins to 5ft 11ins tall, of skinny build and wearing a light coloured balaclava or face mask, grey hooded top and black joggers.
The second offender is described as white, in his late teens or early 20s, 5ft 7ins to 5ft 8ins tall, of skinny build and wearing black clothing including possibly a tracksuit and a black scarf or bandana.
A wallet was recovered in Blaby Close, Abbeymead so it is thought the offenders travelled in that direction after committing the robbery.
Anyone who witnessed the incident, recognises the descriptions or has any information are still urged to call police on 101, quoting incident 504 of February 24.
