A Letchworth shop worker used a baseball bat to chase off a knife-wielding man who allegedly threatened two passers-by.

Police are appealing for witnesses to the altercation, which happened outside the off licence in Ivel Court on Friday, between 7.30pm and 8pm.

They have arrested a 28-year-old man on suspicion of making threats with an offensive weapon, as well as a 37-year-old man on suspicion of affray in connection with the same incident. The men, who are both from Letchworth, are due to answer police bail on September 4.

PC Paul Edmondson, who is investigating, said: “Thankfully the men were not hurt during what must have been a frightening ordeal.

“The victims have not yet spoken to police about the incident and we are keen to trace them as they may have information that can help this investigation.

“If you were one of the victims, or if you saw what happened, please get in touch.”
