At least five suspects were Thursday arrested after they were involved in an abduction incident in Ruaka area, Kiambu County.
A man who was headed home was taken hostage by the gang and taken to Ithanga and Thindigwa areas where he was detained.
When his girlfriend called his mobile phone, a stranger picked it saying they needed Sh500,000 for his release, police said.
They handed him the mobile phone to confirm he was their captive and warned her against involving police.
Out of panic, the woman informed the police who swung into action and traced the gang to Ithanga area and Thindigwa.
By then, some family members of the victim had sent Sh68,000 for his freedom.
Five suspects including a woman were arrested in a house where they were holding the victim, police said.
Police said they recovered a kitchen knife, a shock torch, ten mobile phones of different makes, one tablet, and two motor vehicles.
The victim was also assaulted by the abductors and had visible physical injuries all over the body and a bloodstained shirt, police said.
The victim was taken to hospital for medical attention.
Police said they are investigating to establish if the suspects have been involved in similar past incidents.
