A stabbing incident at Matoshree – the residence of Thackerays in Bandra (east) and one of the most heavily guarded structures in Mumbai – has set off alarm bells among the police establishment. Although the incident involved the cooks and a domestic help of the Thackeray household, police officers are examining whether it could lead to a security breach from within.Matoshree is a ground plus threestoreyed structure in Kala Nagar, Bandra (east). The first floor of the building is currently locked; the second one was the residence of the late Balasaheb Thackeray and is only partially in use now; and the third floor is occupied by Uddhav Thackeray and his family.Confirming the incident, DCP Virendra Mishra (Zone 8), said: “Two cooks – Sewak and Pandit – got into an altercation when Pandit was trying to pull the former’s leg. Sewak lost his cool and attacked Pandit with a kitchen knife. Manda, another domestic help who was present there, got injured. Both of the injured victims are currently out of danger and Sewak has been arrested under section 326 (voluntarily causing grievous hurt by dangerous weapon) of the IPC,” he said. “The accused was produced before the designated court and has been remanded in police custody.”The incident occurred on Saturday night. Both Sewak and Pandit are from Nepal and have been working in the Thackeray household for a long time. Manda, the domestic help who got injured in the melee, is in her 50s.A protection branch official (Mumbai police side branch that is created specially to guard VIPs) posted on duty at Matoshree told Mumbai Mirror on the condition of anonymity that it was a serious issue.“The episode raises questions over the internal security of the Thackerays. The two youths and the injured lady do no stay in the bungalow but the incident exposes loopholes in security. Though it is an internal security issue and the police have very little role to play, the department should take up the issue and discuss it with the members of the Thackeray household and find a solution to it,” the official added.A Shiv Sena MP confirmed the incident and was worried about its fallout but did not wish to go on record. The Sena has for long been on the radar of fundamentalist groups, especially after the demolition of the Babri Masjid in December 1992.Due to high-level security threats, then Shiv Sena chief Bal Thackeray was provided with Z-plus security cover, which included a bullet proof car, a police inspector, two assistant police inspectors, two escort vehicles with six constables in each and 10 constables at home in each shift.After the demise of the Sena patriarch, the security cover was scaled down. But Matoshree continues to be heavily guarded. Besides security personnel, the police have even deployed “watchers” (cops in plainclothes) to maintain vigil in and around the residence.Uddhav Thackeray enjoys Z category security cover which includes one police inspector and an escort vehicle with four constables at any given point of time.
