But detectives have now arrested two men as a pensioner remains in hospital following a violent burglary last month.
A masked raider knocked on the 88-year-old’s Harington Drive home in Weston Coyney at around 6.45pm on February 27 claiming to be a police officer.
When she answered the door she was pushed to the floor and threatened with a screwdriver before the assailant made off with thousands of pounds in cash.
Police officers have now confirmed two men were yesterday arrested in relation to the incident.
A Staffordshire Police spokesman said: “Yesterday (Friday 13 March), police arrested a 27-year-old man from Leicestershire on suspicion of robbery and other offences. He remains in custody while enquiries continue.
“A 52-year-old man from Stoke was detained earlier this month on suspicion of grievous bodily harm with intent and aggravated burglary. He has been released on police bail.
“The victim remains in a stable condition but is said to be very poorly in hospital.
“The investigation’s ongoing and police are asking for any witnesses or anyone with information to come forward.”
Anyone with any information is asked to contact Staffordshire Police on Facebook, Twitter, or via 101 quoting incident 654 of February 27. Alternatively, contact Crimestoppers on 0800 555 111.
