KOCHI: There are indications that employees of Metro Rail or repairing workers who came on contract were involved in the bomb threat on Muttom Metro Yard. A threatening graffiti was written on metro train which was part of Pamba rack after one hour of effort. There was no power supply to the yard at that time. Knowing this, the two-member gang encroached and did such an act.
They must have spent time in the yard, with or without technichian's help. They returned in the same way as they had come in order to avoid suspicion. A bomb squad inspection was held. All five trains in the yard were examined in detail at the time of writing the threats.
The police are investigating the incident, but is still clueless about the attackers. Metro's internal investigation is also progressing. It is also being investigated whether graffiti artists are illegally painting on trains. This is not a popular practice in India.
