Police have arrested a man on suspicion of carrying out burglaries of elderly victims that left a 102-year-old suffering cuts and bruises.
The 47-year-old suspect, from Lincoln, was held on Wednesday and released on bail following the incidents in the Ermine area of city on Tuesday.
Lincolnshire Police said he was arrested on suspicion of carrying out four burglaries and two thefts from shops.
The arrest came after a 102-year-old man told how he fought off an intruder who tried to force his way into his home after telling him: "You're not going to come in here, mate."
The centenarian, named only as John, suffered cuts and bruising when the offender pushed past him into his house after claiming he was there to check the lights.
He and his wife Joan, 97, said they were left shaken up by the incident - the second attack on their home in the last six months.
Lincolnshire Police are investigating the incident at around 1.45pm on Tuesday, along with another in the Ermine area about 45 minutes earlier.
In the first incident, cash and bank cards were stolen after a man pushed his way past a disabled woman in her 90s.
Chief Inspector Phil Baker said:
These two incidents are clearly concerning because they involve elderly and vulnerable victims.
