The Kerala police have arrested a 35-year-old man from Ernakulam who killed his 6-year-old son and buried the body.

Babu, a native of Kodanadu, walked into the Kodanadu police station at 6 am on Tuesday morning and confessed to killing his son, Vasudev. 

The police then recorded his arrest. 

Babu's wife, Raji, had on Monday filed a missing persons complaint after her husband and son did not return home for four days. 

Kodanadu Sub-Inspector, Suvarnakumar, told The News Minute that Babu decided to surrender to the police.

"According to Babu, he hit Vasudev on his head and killed him as the family was facing financial troubles. After killing his son, Babu attempted to commit suicide. Not being able to take his own life, he fled Kodanadu. For the past four days, he has been roaming around in many places including Thirupati," the SI said. 

The police have filed a case against Babu on charges of murder and a team of police officials are on their way to retrieve the boy's body. 

Further details are awaited.
