Wikipedia
The BRÅ has not released detailed data on rape committed by immigrants since 1996, but according to that report individuals with an
immigrant background made up 61% of all rape convictions between 1985 and 1989.

You seem to be interpreting the above as "61% of all rapists have an immigrant background". It says nothing of the sort.
In fact that tells us about
convictions. Conviction rates for rape are notoriously low, so that tells us about
a tiny proportion of reported rapes. It tells us nothing about the total number of reported rapes. According to one source in the UK about 1% of all rapes result in a conviction:

I've not cross checked the above, it matches what I recall reading elsewhere.
From the same Wikipedia source:
"According to
Brå, it is likely that only around 20 per cent of all rapes are being reported"
So according to the source you give we know nothing about 80% of rapes because
the vast majority are unreported.
So, the statistic you quote tells us almost nothing, despite being at first site very alarming. A rough estimate says that 1% of all rapes lead to a conviction. It could be that those raped by an immigrant are more likely to report the rape, more likely to be believed by the police, and more likely to lead to a conviction. Of course it could also be that immigrants are as a group far more likely to commit rape, but there is absolutely no evidence to prove, or disprove that possibility.
That is the problem with statistics, they can be taken to mean something they don't.
And I am concerned that there are gangs of people with a Pakistani heritage who have systematically raped young predominantly white women. But you have to discuss these issues in context, and understand what any statistics are
actually saying rather than deliberately misinterpreting them as part of a "We hate Muslims" or "We hate immigrants" agenda.
