Ashmawy told CBS News that considering the size of the sarcophagus, it might belong to someone important.
But even if the tomb has no connection to the ruler, it is still a significant find as it is relatively rare to find an unopened sarcophagus in Alexandria, according to Smithsonian.com.
The tomb, which dates back to the Ptolemaic period between 305BC and 30BC, was uncovered in the city of Alexandria.
Alexandria is full of ancient Egyptian antiquities, which makes citizens illegally dig to search for these monuments below their buildings. So far, the person's identity remains a mystery.
And to add another one on the list, an old spooky relic was found inside an ancient tomb which is said to be the largest ever seen in Alexandria, Egypt. It most likely belongs to the owner of the sarcophagus, the Ministry said.

For thousands of years, similar Egyptian tombs have been plundered by grave robbers, so when archeologists have made similar discoveries in the past, sarcophagi have often been found ripped open.
Officials hope to learn more when the tomb is opened, but that process won't be easy. The lid of the 265-cm (104-in) sarcophagus is sealed with mortar, indicating that it has not been removed in its 2,000-year entombment. We can not speculate at this point about the identity of the owner, as the exterior of the sarcophagus does not have engravings or drawings.
However, special attention needs to be devoted to the opening of the sarcophagus, and scientists argue that preparation must be done so as not to endanger its content as it is 5 m beneath the surface of the soil and weighs 30 tons.
The next step is for researchers to find out what is inside the coffin without damaging it.
