Police have renewed an appeal for information following an alleged aggravated burglary in Hitchin – and are urging a pedestrian, who they believe may have seen the incident, to come forward.

Intruders were allegedly disturbed at an address at Roundwood Close on Saturday, May 6, between 2am and 2.30am – and a man inside the property was treated in hospital after being injured during the incident.

Officers believe a man was walking down the road at the time of the incident, and may have seen the alleged offenders fleeing from the property.

The potential witness is described as white man, aged between 30 and 40 years old and about 5ft 8in tall.

He was said to be wearing dark blue jeans, a dark coloured top and had bushy hair and stubble. He appeared to be holding a form of takeaway food, and was reported to have spoken briefly to one of the paramedics who was on the scene.

It is thought the incident may also be linked to a second incident around the same time, where a vehicle was broken into in nearby Grovelands Avenue.

Aaron Boyce, 18 – of no fixed abode, but with links to Hertford – has been charged with aggravated burglary. He was arrested on May 6 and remanded into custody. He is next due to appear at Cambridge Crown Court on June 5.

A 33-year-old man from Hertford and a 20-year-old man from Tottenham in north London have been arrested in connection with the incident, and have been released on police bail.

Det Con Jeanette Walker from the local crime unit in Hitchin said: “We are doing all we can to get to the bottom of this offence and are following a number of lines of enquiry.

“Through initial investigations into the incident we believe the man who spoke to the paramedic may have witnessed something.

“I would urge him, or anyone with information about the crime itself, to contact the Hitchin local crime unit via 101 as soon as possible.”
