Four guards were suspended after four prisoners escaped from a jail in Neemuch district in the wee hours of Sunday.
"Four guards have been suspended in the case. It seems the crime has been committed after much planning. They have taken support from outsiders," Neemuch-Ujjain Police Commissioner Ajit Kumar said.
The police have registered an FIR and are investigating the case. Police officers have carried out an inspection of Kanawati Sub Jail here.
Two absconding prisoners were lodged in the jail for drug trafficking while others were sentenced for committing murder and rape, respectively.
All four prisoners cut the bars of the jail with the help of a saw and jumped the wall by using a rope.
A massive search operation has been launched by the jail authorities to nab them.
