A 2-year-old boy from Vairengte in Kolasib district near the Assam border was found dead in a stream on Tuesday after he went missing one week back, police said.

Master Lalsiamthara had gone missing on November 11 from Vairengte near the Assam border when his father Zothanmawia left him with a 9-year-old boy to fetch fuel for his auto-rickshaw from a blacker from Assam’s Lailapur.

When Zothanmawia returned he found his son missing while the older boy, who belonged to the same neighbourhood, was later found in the jungle nearby, police said.

The older boy told the missing boy’s father that he went to defecate among the bushes and told the boy to remain there and promised him to return soon.

He said when he returned, he did not find him.

After a missing complaint, a community search was launched to find the missing boy, police said.

The boy’s body was found lying face down in Tuidaikhur stream about 5km away from where he was missing during a community search on Tuesday around 2.30 pm, police said.

The preliminary investigation showed that there were no signs of injury and being physically attacked, they said.
