Reviewing the security of Brar, who had led the Operation Bluestar against Sikh militants in Golden Temple in Amritsar in 1984, Union Home Ministry officials said no communication had been received from the Army about his travel plan.
The officials said an immediate need was felt for relocating the Army official as his present location had been exposed to Khalistani terrorists.
The security of Brar, who was Major General during the Operation Blue Star, is also likely to be upgraded to Z-plus category from the existing 'Z' category.
78-year-old Brar and his wife were attacked by four youth near Hyde Park in London on Sunday night.
There has been a spurt in the activities of Khalistan terror groups like Babar Khalsa International in the recent past abroad and intelligence agencies suspect the plot to attack the highly-decorated officer was planned in Germany.
"There have been reports that the attack on Gen Brar was planned in Germany on June six on Bluestar operation anniversary. We are ascertaining the facts," a security official said.
Last month, Intelligence Bureau chief Nehchal Sandhu had said that due to the external support, "terrorist groups, including those focusing on Punjab and neighbouring states, are likely to pose a challenge.
Maharashtra government also said it will beef up the security provided to Lt Gen K S Brar (retd), who was attacked by four persons in central London recently.
Brar, 78, had been attacked on Sunday night by some men, suspected to be Khalistan sympathisers, with knives while he was leaving a hotel in London. He arrived at the Mumbai airport along with his wife Meena today.
"We will step up the security cover given to Lt Gen K S Brar. The security will be as much as required," Maharashtra Home Minister R R Patil told reporters on the sidelines of a function here.
Patil added that the state government had provided protection to Lt Gen Brar (retd) in the past as well.
Brar had led Operation Blue Star to flush out pro-Khalistan Sikh militants from the Golden Temple in 1984.
