Femi Fani-Kayode, former minister of aviation, has warned protesters against the second wave of EndSARS protest.
The second wave of End SARS protests on Monday commenced in Osun and Oyo States.
In Lagos and Calabar, teams of police officers and soldiers have been deployed to the streets to forestall a breakdown of law and order.
Security has also been heightened in other states in Nigeria.
Reacting, Fani-Kayode warned protesters to be very careful.
He said he got information that security agencies will be ruthless and not hesitate to take lives.
Fani-Kayode, on his Twitter page, wrote: “Those that wish to come out to protest for #endSARs again need to be circumspect & VERY careful.
“I have it on good authority that this time around, the security agencies will be merciless, ruthless, and totally unrestrained. They will not hesitate to take life. I advise caution.”
