No it is not true.
During an experiment called OPERA at the large hadron collider in CERN, where a stream of neutrinos was tracked, they thought they'd found a few that clocked out at just a shade over the speed of light.
To their credit, the experimenters doubted their own findings; so they went public right away and asked for immediate peer review. In a matter of hours after going public the email was filled with critical analysis of what the experimenters had done and their results.
The first critical rebuttal of the results I read indicated the experimenters failed to account for relativistic effects, which, even for something as tiny as a neutrino, can be significant. Apparently others have criticized the optical cable they used and its effect on the results. [I've not read that one.]
In any case, the consensus is that, no, neutrinos still do not go faster than light and Einstein, Michelson, Morley, and Maxwell are all still safe in their work.

Yes, it was reported that they've found neutrinos traveling faster than the speed of light, but it was an anomaly in the equipment.
P.S.
Tachyons are hypothetical particles. There is no proof to support their existence.

They thought they had found that neutrinos could travel slightly faster than light. But it turned out the measurements were wrong due to an equipment fault (optical fibre cable connection I think).

They've known about tachyons a while - it's not a Star Trek invention
