THREE arrests have been made as police continue to search for two men who robbed a grandmother at knifepoint.
Police have stepped up their presence on The Stour in Daventry following the robbery, which happened on the night of November 19.
As yet the masked men have not been found, but three other people have been arrested for alleged drug offences.
On Friday, November 25 and Saturday, November 26 an extra 40 officers were deployed to the street, on the Grange estate, to provide reassurance patrols and execute three search warrants.
Over the two nights a small amount of cannabis was seized along with several offensive weapons.
A 20-year-old man was issued with a cannabis caution and accepted a referral for drug treatment.
An additional 10 officers and a drugs dog were drafted in on Thursday, December 1 after police left letters at every house on The Stour appealing for witnesses.
This led to three people being arrested - two women in their 20s and a man aged 24.
All were arrested on suspicion of being involved in the supply of Class B drugs.
Sergeant Sam Dobbs, of Daventry district safer community team, said:
“We are grateful for the number of residents who have come forward to assist our investigations, clearly appalled by this incident (the robbery).
“Fortunately incidents of this kind are extremely rare in Daventry, which remains a very safe place to live.
“A combination of crime investigation and community policing will ensure it stays that way.
“Once again I am appealing for the public’s help in identifying the offenders, who are described as white, around 5ft 10in tall and of medium build.
“They made their escape via
the rear gardens of The Stour, just before midnight on Saturday, November 19.”
Witnesses to the robbery, or anyone with information, should call Northamptonshire Police on 101 or Crimestoppers anonymously on 0800 555 111.
