Security has reportedly been heightened at the West Kenya home of President Obama's grandmother following the killing of Al Qaeda leader Usama bin Laden.

Additional police officers have been stationed at the Kogelo home of Sarah Obama following fears of a reprisal attack in retaliation for the killing of bin Laden on Sunday, Africa Review reports.

"We've received reports of plans to attack the home of Mama Sarah Obama three days ago and immediately put in place adequate security measures," local police chief Stephen Cheteka said, adding that the home will be under constant surveillance.

Cheteka said there was no cause for alarm and that Obama had been informed of the increased security measures.

Calls to the U.S. State Department seeking confirmation of the report and additional comment were not immediately returned on Tuesday.
