Police claimed to have had sent the file.
As have-had is used to connect past with present then how this sentence make any sense??

Unless it is a clumsy word-order swap on, 'Police claimed to have had the file sent', that sentence is not right.
The "have-had" combination is not a problem in some circumstances:
"I have had fish that wasn't quite fresh, and it was awful,"
or
"We have had to reconsider."
But in the past perfect verb tense we use either "have" or "had" (not both) followed by the participle of the main verb. And we can't stack up the "have"/"had"s and follow the second one by a main verb to make a "double past perfect tense". "Double pluperfect" doesn't exist. English doesn't support any tenses farther back (into past events) than the past perfect.
If you ponder it, you can think of a situation where someone might want to use that "tense". For example, suppose the police chief said,
"We had already sent the file by the time the FBI asked us not to."
Then a reporter might want to write,
"Police claimed to have had already sent the file before they were instructed not to."
or,
"Police claimed to have had sent the file already."
But it wouldn't be right. In English you can't say that.
